[weak moss]

i thought it was just for data stats

[radiant siren]

Hello, im looking for a simple plugin to protect the spawn on my survival server that folia supports. It sounds super simple but its taken me... Way too long... any ideas? Something like this but with folia support: https://dev.bukkit.org/projects/spawn-protect

[unique quail]

https://hangar.papermc.io/CORE/CoreProtect

[radiant siren]

you can use coreprotect to make it unbreakable?

[unique quail]

Has anti-griefing in it so I'd guess it would

[radiant siren]

hmm ill look into it

ty

[radiant siren]

nope, my question still stands, specifically i need it to protect the area from breaking blocks :P

[radiant siren]

Im trying command blocks but those arent working either...

[viral stone]

yes, those don't work

as is covered by the docs

oh, i thought that was more doc'd

[radiant siren]

oh ty

[radiant siren]

My server launches in 3 hours and I still havent figured it out...

[finite hinge]

WorldGuard has a PR with Folia support I think

Otherwise just vanilla spawn protection

[noble flower]

Is anyone running a folia production server? Curious to see how it's performing with players.

[radiant siren]

Neither work. I think ill just get rid of the spawn build :(

[pseudo ibex]

Yea see here is the WG PR. You can build it here https://github.com/EngineHub/WorldGuard/pull/2012

It should work, although if it doesn't here is one - https://github.com/Folia-Inquisitors/WorldGuard-Fork

I see you also mentioned command blocks not working. There are plugins that try bridging the gap, and can act like command blocs, but more efficient. One that I use is called BloCommands. https://github.com/Folia-Inquisitors/BloCommands

[radiant siren]

Thanks so much, sorry to bother more but any one player sleep plugins? Suprisingly I havent been able to find any...

[livid crag]

It is a gamerule now for vanilla so it will also work for Folia.

[radiant siren]

tysm that took me too long lmao

[weary whale]

Hello guys. What do you think when folia will be officially released? So we can run our server on a Xeon cpu and 16 cores….

[tacit tartan]

There's no timeline, work happens on folia when Leaf can

[weary whale]

Okey. How far has it been developed yet? I got a folia jar from my dev and yet it seems to work fine. Despite of almost no plugins are working 😁

[tacit tartan]

Somewhere there's a list of known not working systems, I know scoreboards are on there, pretty sure multi-world support is too. Probaably a bunch of other minor things

[weary whale]

Okey, thank you.

[trail heath]

[pallid axle]

Does folia have any special configs that affect the number of mob spawns in the world/regions?
We have 2 projects, one on paper and one on folia. And the general configs are often the same, the folio is set to 400% (threads)
Mobs spawn very unevenly, sometimes there is spawn, sometimes not. Rebooting often helps (to the game, to the region), but this is not normal

[viral stone]

No

folia also gets rid of papers per player mob spawning and basically makes it per region

Welcome to mob spawning on servers pre that feature

[pallid axle]

I understand correctly that previously mobs spawned in a sphere of 128 blocks around the player, but now the mob cap is spread over the region, and spawning on a big count of chunks around

[viral stone]

No

previously mobs spawned anywhere a chunk was loaded and there was a player within 128 blocks

and then that same rule assuming the nearby player din't have more than X mobs around them in a range

folia removed that extra check, but limited the thing to "any loaded chunk within a region upto a limit decided by the maths"

rather than a limit for the world as a whole

mob spawning on servers has always been janky, I think mojang kinda adopted out per player stuff but that's also likely missing from folia due to how it all works, etc

[random garnet]

https://github.com/BlockhostOfficial/folia-plugins

[pallid axle]

extra check is a cap in sphere? or spheres exist and add up and have common cap per region?

[viral stone]

per region cap

rather than a per world cap

[pallid axle]

but spheres exists

[viral stone]

only for determining if a mob can spawn at that specific spot in the world

It's not "try a space within 128 blocks of a player"

it's "try a space in the world and see if a player is nearby"

and, it runs off the chunk list, and so somebody generally just naturally gets a bias of the mob spawns

[pallid axle]

Thanks

[livid crag]

This is a good introductory video and just use this video as a base and, on Folia, each active region is completely separate from each other with its own spawning loop.
https://youtu.be/ShrG24eWC7g

[prime juniper]

Hello! Can you please explain. The server is using folia. The problem is that playing on the server - almost no appearance of hostile mobs. Namely, players build their farms, which on another server show high scores. But on the server that uses folia - players have noticed that on their farms do not appear hostile mobs, and if they appear, they are 5-10 pieces. All server settings are standard, as well as on a similar server that does not use folia. The question is how to increase the number of hostile mobs appearing on each player? At the moment it feels like all players share the maximum number of appearances of hostile mobs equally

[livid crag]

literally read above ^

we were just talking about it

[pallid axle]

hmmm
case 1. i spawn hoglins and go away for 200 blocks and go back -- they exists, but i think they should have despawned
case 2. friend looks at the hoglins in the spectator and I do the same -- they despawn
in case 1 I am alone in the region, in case 2 there are only two of us, but one in the spectator

hoglins in case 1 uses region cap? what about sphere? why in papper with same settings i see near >20 hoglins on platforms, but on folia 3-5

* hoglins are specific case. common mob farm doesn't work well too (or not work at all)

[livid crag]

Are you running the default Vanilla config? this is very important

as in simulation distance and view distance both at 10 etc

[pallid axle]

i think
if I am alone in the region, my cap == region cap, but... in case 1 mob does not despawn, what about region cap?

[livid crag]

You cap will always be region cap if you are alone

[viral stone]

You don't have a cap

your region has a cap

[pallid axle]

simulation 5, view 10, and this settings are on both servers: papper and folia. and papper works fine

[livid crag]

that would explain why your piglin does not despawn because you run sim 5

[viral stone]

Because paper has a set of extra limits over the top of the world spawn limit to try to balance spawns out

[livid crag]

Paper works fine because of ^ and the fact mobspawn loop is done as a whole.

[viral stone]

Folia moves the mob spawning dynamics back to like 1.18 or so, or whatever version it was before paper (and then mojang) added the per-player limiting stuff

[pallid axle]

by this guide
by default, i have cap and world can cap
you says, that world cap moved to region cap, i.e. no world cap, but what about player's cap? where did it go?
I'm expecting region cap and player cap

[viral stone]

There is no player cap

that was removed

[livid crag]

as Cat explained, it no longer exist.

[viral stone]

for the 200th time

[pallid axle]

oooow

sorry

[viral stone]

mob spawning on paper works by:

1. checking if we've not met the world cap
2. getting a random point in a loaded chunk in the world
3. checking if a player is within 128 blocks of that position
4. Checking that the player doesn't have their cap worth around them

folia doesn't have step 4, and so you enter the old state where a single player within a region, rather than a world, can eat all the mobs

[pallid axle]

ok, i understand
thank you ❤️

and different regions have own caps
cap in region are common to players

mobs spawn only in the sphere and only if the region is not completely cap

I'm right?

[random garnet]

so farms in folia will be slower???

[viral stone]

if you have multiple people in your region that is a potential, yes

and I've explained it all I can, I'm disappearing as my vision is starting to get oddly blurry

[random garnet]

uh okay is it possible to buff that / increase spawn rate

[pallid axle]

Do I understand correctly that mobs are counted in all chunks in the region if they are not despawned for some reason?
spawn only in sphere, but count all of them

[inner swift]

Yes, that's right

[prime juniper]

Пиздец

[livid crag]

watch the videos I linked above

it goes over the very basic idea of mobspawning

[pallid axle]

Yes, but it about normal version. (and works perfectly on paper)
in which version did the player cap (spheres) appear?

[livid crag]

it works on Paper because the loop is global, also what cat say about additional patch Paper has.

Also you are running sim 5 that's pretty bad because that's 80 blocks and hard despawn range is 128 and that's why you see the pigman dont despawn

[pallid axle]

I'm sorry for this whole discussion,
Thanks a lot

[random garnet]

what abt this

[livid crag]

Nope.

As the video explained your spawn rate is just your TTK speed and that’s largely a farm design problem

The game is already checking monster spawn per tick

[finite hinge]

If you increase the cap the farm probably just fills up even more and doesn't really change things for everyone else

This is yet another reason to get people spread out

Or at the very least get them to hop into the nether, run 300 blocks, go back to overworld, and build their farm there

[odd juniper]

Ok, I feel pretty stupid atm, but I cannot find the download link for folia?
the downloads page leads to downloads of other paper software, i.e. https://papermc.io/downloads/paper or https://papermc.io/downloads/waterfall, but clicking on folia just leads to the software page https://papermc.io/software/folia

What am I missing here?

[tawdry gull]

⚠️ Please do not share any links to builds of Folia at this time. We are intentionally not providing easy to find/obtain downloads right now - when the time is right, everything will be available through official PaperMC distributions.

[tropic otter]

what did i do wrong?

[pallid axle]

at what distance folia unites regions?

and what is the default radius of the region?

[livid crag]

There is no cutoff distance as that is determined by many factors but roughly within ~1500 ish blocks. The number is not something set in stone as your question is suggesting.

[viral stone]

you need to basically apply patches from the console or whatever, doing it with IJ open especially inside of windows is known to cause issues

[spark ingot]

Hey is ther a way of changing "Implementation variables" for the regioniser to split groups of chunks more aggresivly like 300 block away from a existing region?

[viral stone]

Basically, no

[spark ingot]

oh . . .

[viral stone]

the distances stuff is pretty tied into how the thing works due to the promises that the system has to have, and trying to minimise contention, etc

[spark ingot]

thx for explenation

[pallid axle]

do you plan to turn back per player cap in the region? region cap + personal as in papper whare world + personal

[fair merlin]

For mobs?

[spark ingot]

My plan is to spread out as many players to as many cores as possible on a small map.

[fair merlin]

With Folia you need players spread out 1500 blocks or more.

Otherwise you should use Paper.

Folia's not designed for small maps.

[plush burrow]

I can download the official compiled build?

[jagged ether]

You have to build it yourself

[spark ingot]

But could it handle 300 or so players on a 1400x1400 map with 3.5ghz 8 core CPU?

[fair merlin]

No.

Too many players, in too small of an area, on too weak of a CPU

[viral coral]

way too small

[viral stone]

it's technically on the API but we don't publish links to it, the expectation is that you're capable of compiling or yourself as it's not really in a state you should be running it

[plush burrow]

8 cores is not enough

[plush burrow]

okay, I just don't use gradle

[viral stone]

the cores is literally irrelevant at that point

[pallid axle]

this question for developers
Are there any plans to improve it?

[livid crag]

Ofcoz but it isn’t a priority rn

[pallid axle]

do you have a public roadmap? what is your current priority?
ooooor folia is so super test product that even this has not yet been formalized

[fair merlin]

No public roadmap or priority list.

[pallid axle]

ok, thx

[livid crag]

Also it can be mitigated as we discussed last night.

The farm design just need to have faster TTK

it may help if you delete the .gradle folder in c:\users\user directory
as i recommended earlier lol

[patent acorn]

to compile folia i asume i must run gradle.bat?

[naive junco]

./gradlew applyPatches, then ./gradlew createReobfBundlerJar

[patent acorn]

im not on linux...

[naive junco]

You don't need to be on linux

https://www.youtube.com/watch?v=oTh9DjFgmTM&t=475s

[patent acorn]

you litrely tell me to run a linux programm

[daring nimbus]

my recommendation would be to use WSL then, Windows is slow and has fun file-locking issues.

generally you can refer to the contributing.md document in the Paper repo, its the same process for Folia

[naive junco]

The video shows you how to compile folia, those exact steps worked on my Windows 11, only difference is I set my folia directory at C:/, not at the default dir, since that kept giving errors.

[patent acorn]

my wsl broke

why did you put a timestamp in the video link...

[fair merlin]

The Paper repo has the instructions you need.

You shouldn't need a whole youtube video.

[digital relic]

You can use it on windows

[patent acorn]

No shit sherlock

[digital relic]

?

[patent acorn]

Theres a litrel batch file ofc i can compile it on windows

[viral coral]

if you're going to ask for how to compile it on windows

cut the attitude

[patent acorn]

I DID NOT

I JUST ASKED IF I WAS DOING THE RIGHT THING

[viral coral]

the answer is no

[patent acorn]

i mean i alredy found that out

anyways this topic is closed and just dont respond

[foggy blaze]

no

[pseudo tendon]

how much better does folia perform on a survival server with 100~ players is it worth it to switch and to recode all the plugins?

[feral hazel]

Are your players apread out across the world or do many players play relatively close to each other?

[inner swift]

Depends on this and your hardware

[pseudo tendon]

spread with a border of 8k x 8k

[inner swift]

Will likely be worse than Paper

[pseudo tendon]

i9-13900K

[pseudo tendon]

and with 200 players?

[feral hazel]

That's not far, but if you have the hardware there could be minimal improvements. Whether it's worth the effort - idk

[inner swift]

You should not be running Folia with players that close

[lofty magnet]

you should have at least 1k blocks between player (groups) iirc

[feral hazel]

more then 1k blocks i guess

[inner swift]

If players are less than about 1500 blocks apart from each other, they are guaranteed to be in the same region

[lofty magnet]

damn, it was even higher than what I remembered lol

[inner swift]

With an 8kx8k border and 100 players you will likely have one big region

[pallid axle]

does folia work with rcon?
we are trying to set up voting rewards (mineserv.top), but the response is null
connect successful, but...

is there a guide for connecting and setting up? on the paper is configured and working

[hexed ice]

rcon doesn't work

i would also not trust a voting site with full access to any command on my server

[lofty magnet]

I strongly doubt they really do that... but it's all russian so I can't read shit on their site xD

[pseudo tendon]

So when would it really be an improvement?

[feral hazel]

If your map is very large and your players are around 1500 - 2000 blocks apart or there are only a few players within a region

[viral stone]

When you actually have the ability to have multiple regions ticking

as per the entire point of the software

which relies on you having the correct amount of player spread

[pallid axle]

can we expect it or are there alternatives?

[hexed ice]

yes, a plugin like (nu)votifier

don't know if that supports folia yet but that shouldn't be much of an issue

[pseudo ibex]

I think there’s probably forks that do. I have a NuVotifier fork that does

[pallid axle]

rcon planned?

[pseudo ibex]

I don’t used rcon so I haven’t looked into it

I know voting plugin does

[pallid axle]

Not only voting is needed, there are many features that I want to include

[viral stone]

I mean, can't speak for leaf, but given that the mechanism is crap and its usage is generally limited to niche/weird setups, especially as it doesn't work with async commands, etc; I'd imagine that if there is literally a single ounce of care to fix it, that it's where other than ultra bottom of the list

[tall marsh]

When paperd /s

[pallid axle]

do you have a list of planned features?

[viral stone]

There is a todo list

outside of that, no

[lusty mica]

What the hell is tis'

[feral hazel]

do you mean folia?

[lusty mica]

Yes

Wassdis

[feral hazel]

Read this: https://docs.papermc.io/folia

regionized Multi-threaded server software

[lusty mica]

I'm reading

But what does regionized multi-threading mean?

[zealous sage]

Check the pins, read the docs

[lusty mica]

Okay okay I see

It's like a multi-threaded software

[feral hazel]

This is also written in more detail here: https://docs.papermc.io/folia/reference/region-logic
Folia creates several regions in the world that all tick individually. In Paper the whole world ticks individually, which leads to lag for many players

[lusty mica]

Is there a way I could make my plugin(s) folia-compatible?

[feral hazel]

yes

[lusty mica]

Aha

How so?

[naive fable]

Read the docs

[lusty mica]

I see the api

But I'm more of the

No main thread

What now

Guy

[feral hazel]

There are no docs on this (mean Development Guide). But everything works relatively the smae as with Paper. The biggest point is probably the schedulers: https://github.com/PaperMC/Folia#api-plans

Of course the logic of your plugins also needs to be rebuilt so that they work thread-safely. But that has less to do with Folia and more to do with your plugin

[lusty mica]

Nuu

I'm confused

What is Velocity?

Like bungeecord with another name and api?

[feral hazel]

A modern proxy software in return for Waterfall. xD

[feral hazel]

Yes could say so

But the performance cannot be compared

[lusty mica]

Like literally or you mean it's that much faster?

[feral hazel]

A lot a lot a lot!!

https://docs.papermc.io/velocity/why-velocity

[lusty mica]

Does it have an antibot implemented in itself?

[feral hazel]

do you mean crashes or simply programs where 50000 players connect to your server?

[lusty mica]

Any sort

Cuz if no

I know what amma do tomorrow

[feral hazel]

Velocity can easily manage four-digit player numbers if your hardware cooperates.

[lusty mica]

Add Velocity support to AlixSystem

[lusty mica]

Uh

Buttt

I can still add an efficient antibot, right?

[feral hazel]

This is not integrated into Velocity. But there are definitely plugins

[lusty mica]

Or rather create, I should say

[feral hazel]

yeah

So as a plugin

The Velocity API is extensive

you can build whatever you want there

[lusty mica]

I made like a Paper/Spigot antibot

Cuz I've never seen anyone do a proper one for those

[feral hazel]

Have lots of fun with it. Post it on hangar (:

[lusty mica]

What's that?

[feral hazel]

[viral stone]

Yes

you need to use the paperweight snapshot

[calm fable]

how do you mean?

[viral stone]

there is a bug

that bug is fixed in the latest paperweight snapshot

I can't help much more

[calm fable]

where do i find this snapshot?

if you dont mind me asking

[viral stone]

you'd need to update the build.gradle thing, 1.5.7-SNAPSHOT

and maybe add the paper repo to the settings file, idk

[calm fable]

ok i will try that, thank you

[restive crane]

does folia use NMS or not?

or is it built from the ground up

[viral stone]

it uses mojang code

[tacit tartan]

Folia is just a fork of paper, so yes NMS is present, but I wouldn't expect leaf to be caring too much about paper <-> folia NMS compatibility

[viral stone]

and lots of heavy patches

[restive crane]

ok thanks for the information

Im just wondering why we use mojang's code.

[spare tendon]

cause we have to? to control the game...

[viral stone]

Because the alternative is basically writing an entire server from scratch?

[spare tendon]

We write our own code on top of it, but ultimately we have to interface with something

[viral stone]

See literally every other project which has done that and has basically gotten nowhere outside of being suitable for minigames?

[restive crane]

at some point wouln't that be better than what we have?

[viral stone]

I mean

[restive crane]

I see

[tacit tartan]

Probably, but the amount of effort required to create that is insane

[viral stone]

theres literally an entire wiki page of projects which have done then

none of them are even close to 2% mojang feature compat

[spare tendon]

is there any that haven't died?

[tacit tartan]

Does minestom count?

[restive crane]

I think minestom is doing great

[viral stone]

for a niche set of stuff

[restive crane]

I understand

[viral stone]

it's not something you use for survival servers

[tacit tartan]

AFAIK minestom is still puttering along but it's in no way a replacement for mojang code

[restive crane]

I just think that it would be worth it a some point to seperate from NMS completelly to remove complication and overhead

[viral coral]

it would be more complicated to move away from nms

[restive crane]

but I also understand why we don't do so at the time being

[viral coral]

not to mention minestom is still on 1.19.3 so wouldn't exactly call that doing great

[calm fable]

that worked thank you!

[viral stone]

it wouldn't ever be worth doing that

if you wanna do that, go use one of the many already threaded to heck impls like minestorm

[restive crane]

minestom-ce is a fork of minestom for 1.20.1

[viral stone]

as soon as you ditch NMS, you lose a lot of stuff

entities

blocks

all of the chunk gen stuff

datapacks, etc, etc, etc

there is a reason why none of the "no mojang code" pieces of software generally only get so far or gain traction in generally a "niche" area like minigames where missing all of that functionality is literally irrelevant

[restive crane]

I understand so for the standart user its better to keep nms

[viral stone]

not to mention the years of effort that would be required to basically implement all of that stuff from scratch, especially if you wanna maintain cleanroom

[restive crane]

indeed

Is this cpu enough for Folia?

And 128gb ddr4 ?

[modern plume]

is there any direct link to download folia 1.20.1 without building?

[jagged ether]

No

[daring nimbus]

That CPU is nine years old

You still need at least decent single core performance, unless you have like 1 player per region. And that CPU doesn't have that

[lyric cipher]

There is a github repo which builds folia daily, but i think the time googling it will be same time to build it on your own

[formal shuttle]

[spark ingot]

Umm I have a question. Is that normal that comand blocks don't work or is it just me?
( and yes I have then anebled in properties ) No erros or notifications they just don't work.

[livid crag]

They do not work on Folia

[spark ingot]

Form a friend: "is there a way to make command blocks work tho?"

[fair merlin]

No.

[livid crag]

Replace its functionality with plugins.

[spark ingot]

Could you please recomend any?

[hexed ice]

we can't recommend anything if we don't know what you need

[spark ingot]

I would need a way of automaticly executing commands ( also from plugins ) to assign players to teams.

[feral hazel]

you have to solve this with commands that are executed and can't you do it directly via the api?

[spark ingot]

Well it'll be very hard to copy and paste 400 commands in span of seconds

+-

[fair merlin]

You probably want to make a plugin that does whatever you're trying to do.

There aren't any command blocks in Folia.

[spark ingot]

Oh dear

[spark ingot]

Thanks for the advice tho

[inner swift]

Noting that scoreboards do not work in Folia, and the /team command is disabled

[spark ingot]

What why its disabled>

?*

[arctic tapir]

relies on a global state etc etc etc

[spark ingot]

ohh

Heck

[pseudo ibex]

Hahah why did you thumbs down the pr 🗿

[arctic tapir]

bc it's a snapshot

[pseudo ibex]

I did test putting 1.5.7, but it didn't work. When I put it to the 1.5.7-SNAPSHOT it did finally compile however after it originally did not. Some reference links are here #folia-dev message https://repo.papermc.io/service/rest/repository/browse/maven-public/io/papermc/paperweight/paperweight-core/

[viral stone]

It’s a snapshot

Leaf did not want to update to a snapshot release once we asked

[pseudo ibex]

Oh alright so I should close it?

[viral stone]

[pseudo ibex]

[silver sierra]

@tranquil epoch doesn't know anything about snapchat versions

[prime juniper]

hmm snapchat 💀

[arctic tapir]

what

[random garnet]

i have an old version of folia complied inn a folder

how do i update it

without recompiling a new 1 in a new folder

[viral stone]

git pull

[random garnet]

how do i do that in windows

[viral stone]

in git bash or whatever

[random garnet]

no 1.20.2?

i did git pull so now i have to build again?

[viral stone]

Well, yes; you just sped up step 1, you need to do all the steps

[opaque kite]

Are there any store plugins for Folia such as tebex yet?

[strange nymph]

Does Folia help at all if all of the players are in like 1000x1000 or 1500x1500 area?

[feral hazel]

no

[finite hinge]

They need to be at least 1500 blocks from each other for Folia to help

So in a 1500x1500 you're probably getting one region and then just getting a slower Paper with less features

[trim ridge]

Folia doesn't support numa nodes?

[viral stone]

I mean, java doesn't really expose it

not to mention that would be a huge chunk of architecture to deal with

[trim ridge]

Oh since I got 4 numa nodes

Alot of waste :/

What should I do for a many threads but slow speed processors

[fair merlin]

Not run Minecraft on it, generally.

Minecraft wants a high clock speed.

Even Folia would want high clock speed if NUMA were supported.

[trim ridge]

Cus my machine got alot of threads

I mean damn alot

[fair merlin]

Not great for Minecraft.

Web server, some other linux server, etc maybe?

[trim ridge]

160 threads

Or should I just disable multithreading and overclock it?

[fair merlin]

You should probably run just Paper and get a different CPU.

[trim ridge]

It got a overclocking feature inside it

Oh

But like what should I do with this one

Run dbs?

[fair merlin]

Dunno. Whatever you want I guess? Not really a Folia question.

[viral stone]

I mean, NUMA is all about data locality

[trim ridge]

To be honest I think I dont even need Folia when I got like 50 online

[viral stone]

the only real cost is that you've gotta deal with the caveats of accessing memory across NUMA regions which isn't the fastests but is generally not the end of the world so long as it's not cross CPUs entirely

[trim ridge]

It got 2 numa nodes per cpu

DCM

[inner swift]

Uh, did you buy this specifically for Minecraft?

[trim ridge]

No but

Just got curioused

[inner swift]

Fair

[trim ridge]

So threadripper would be decent?

Rn im using threadripper pro 3945wx

[fair merlin]

Pretty sure that's lower than the minimum core count we recommend for Folia.

Also depending on your use case you may just want to use Paper anyway. Players need to be >1500 blocks apart to take advantage of Folia. And you need a lot of RAM.

[prime juniper]

Can Folia also be used for 1.20.3?

[subtle oriole]

.3?

[viral stone]

I mean, given that there isn't even a .3, no

[ancient monolith]

what flags should i use to run folia

[rustic imp]

what is this

[viral stone]

advice atm is basically to just use aikars flags with a bunch of ram

[tawdry gull]

Folia

Folia is a fork of Paper that adds multi-threaded region support. Many plugins will require updating to support Folia. There is no ETA for publicly available builds.

For more information:

• Readme
• FAQ
• Regionising logic
• Detailed overview
• Javadocs

Folia will:

• NOT be backported to older versions <1.19.4
• NOT be merged into Paper
• NOT be ported to Fabric nor Forge

Stay tuned to #announcements for any further info about releases.

'ETA' means 'Estimated Time of Arrival'!

[jaunty compass]

Can someone help me?
My server kills itself when I leave it on for too long
no logs or anything just "Killed"

[feral hazel]

do you use folia?

[jaunty compass]

Yes

[feral hazel]

since folia does not have a stable release, what is the last git commit of your folia?

[jaunty compass]

"edafbce"

[viral stone]

"killed" means that the process was killed by something

generally the kernel as it ran out of memory

reduce Xmx

[jaunty compass]

Okay

[trim ridge]

128gb of ram

Let's gooo

[jaunty compass]

I have 4

[charred iris]

yeah that would explain it

[crimson folio]

I assume you have a host with an OOM killer enabled. (oom = out of memory)
You'll want to reduce your xmx arg as stated above
If you want an amount to try, since I assume you don't have experience dealing with this, try reducing it by around 1GB and mess with that number over time.
(yes it will feel like you are paying for ram you can't "use" but that's just how it works 🤷 )

[fallow stone]

Is folia good for a 20000x20000 world?

[viral stone]

if you have the correct player spread, yes

[feral hazel]

do your players move within this radius or is the world just that big?

[fallow stone]

They move a little but mainly settle pretty far from each other, it's a nations server.

[feral hazel]

if your players are all relatvely spread out within this radius then you should have advantages through Folia

[fallow stone]

aight, sounds good, thanks man.

[feral hazel]

👍

[royal swallow]

Does anyone know why the head is like this?

Is Minecrafts head-service down or something?

Explanation: Head does not have the "skin" in inventory, but has when placed.

[finite hinge]

I would guess the head didn't get the metadata set correctly on the item but it was close enough that the item->block conversion was able to fix it up

[cold latch]

hey all, is there a resource anywhere about all the documented tests on different hardware with different situations?

I've seen some Cubxity blog stuff for the higher end, and but was hoping to find out more about the lower end

[viral coral]

no one has done lower end tests and publicly posted about it

because you probably wouldn't want to run this on lower end hardware either

[cold latch]

at what level would it be considered a waste of time

[viral coral]

what hardware do you have

[cold latch]

I'm currently weighing up options, especially from this line https://www.hetzner.com/dedicated-rootserver/matrix-ax

They list the Ryzen 5 3600, Ryzen 7 7700, Ryzen 7 7950X3D

[viral coral]

how many players

[cold latch]

I've seen the testing with the last X3D

and im starting a project from scratch

so currently none, but the point is to be able to scale just based on hardware changes

[viral coral]

are you designing a gamemode around folia

because depending on your usecase you might not even want folia

[cold latch]

Yes, tldr it's a SMP but specifically designed to spread players out

but has many more features on top of the "SMP" im just tldring it

[viral coral]

would just get the 7700 and call it a day tbh

[cold latch]

if I started a beta on the 3600 would it be worth it? what sort of player count could be expected?

like, would it be going backwards compared to paper?

the way it's described in a few places makes me think it'd be worse on certain situations

If I'm custom coding everything for Folia support anyways

[viral coral]

if the only thing you're hosting on that 3600 is a minecraft server and nothing else that would be eating resources

depending on the settings used you'd probably be able to get it to atleast a hundred players

[cold latch]

okay sweet as, that sounds about right for what we need at the start

what sort of gains would there be on top of that if I went with the 7700 instead?

[viral coral]

you get more cores out of it

so you can either hold more players, more entities or run something alongside like a small database / proxy etc.

[cold latch]

okay sweet as

thanks for all the help

[viral coral]

by no means recommended to run with low core counts but with the right settings it can be done

[cold latch]

oh yeah, we're purely running folia for the beta (with low specs) purely because we want to save money while we do testing

[inner swift]

Conside Hetzner's i5 13500 for starting over the 3600

Just beware of the E cores

[cold latch]

I looked into that, it had a lot more cores but also had like half the single thread score

[viral coral]

13500 probably isn't the worst idea especially since you could run some less important stuff on the side on those e-cores

[cold latch]

I had made the assumption that would damage stuff too much

[viral coral]

but it's a bit more of a hassle

[inner swift]

Uh, the 13500 definitely has a lot better single core perf than the 3600

[viral coral]

e/p core scheduling is not great on linux yet, it lacks the intel thread director patches in the kernel yet

p core wise it'll definitely beat the 3600

[inner swift]

So like, if you disable the E cores, it'll still beat the 3600, and they're about the same price depending on your config

[cold latch]

my bad was comparing to the wrong one

[viral coral]

you can disable the e cores for scheduling and manually schedule processes onto it which makes it interesting

[cold latch]

you're right

I do plan to have a DB so the e core would be useful for that

[viral coral]

yeah if you're willing to get your hands a little dirty then taking care of the scheduling yourself makes it a pretty good bang for buck cpu

[cold latch]

I wonder if there are certain types of threads (eg out of the following) if certain ones don't need a huge amount of performance so using the E cores with them

Initial Thread Allocations

GC: 3 concurrent
Chunk System IO: 2
Chunk System Worker: 1
Netty: 6
Region Threads: 6

I'll have to test things in the future when I get the hardware

[viral stone]

given that theres basically 0 mechanism for saying where you'd prefer individual threads end up, basically, that's not how it works

[cold latch]

ah okay

that's unfortunate

but probably makes sense

[jaunty compass]

Does anyone recommend VPS or cloud host that's less expensive than digital ocean? It seems like I'm paying a pretty hefty fee ($28) for a pretty low speced server (4 GB ram and 2 vCPUS). Is that just the cloud norm?

I don't need anything powerful really, just 8 GB of ram so I can (attempt) to host velocity and a lobby?

[inner swift]

This is not for Folia, right?

[jaunty compass]

This is

I mean it could work for paper too but I use folia so I posted it here

[viral stone]

I mean, with cloud you pay a premium to turn it off

using hardware that underspec'd for folia would also be kinda moronic

[cold latch]

it would just hurt performance no?

[viral stone]

yes

[jaunty compass]

I can host it on my own but my wifi isn't great so it has a tendency to kick people off or freeze

[cold latch]

Folia has a bit of overhead so unless you're benefitting from it there's not much purpose

why are you wanting to use Folia?

[viral stone]

I read wife, and was like, wat

[cold latch]

lmfao

"my wife kicks people off the server"

[jaunty compass]

My service only allows me to upscale using more vCPUs which aren't levarged by normal mc right?

[viral stone]

Folia comes with sizable overheads

i.e. the cost of a ticking region is more expensive than ticking an individual comparable server

[cold latch]

correct, but you're using such a low end spec it wouldn't gain much anyways

[inner swift]

Let me be sure, you are only hosting the proxy and velocity in that VPS, which will be connected to Folia in another server?

[viral stone]

you need extra cores, and a decent number of them, to actually be able to benefit from folia

[jaunty compass]

No the minecraft server, and velocity in the same server

[inner swift]

Oh well, then what the others said

[cold latch]

why are you needing velocity for just a single server?

[jaunty compass]

Then I'll see what I can do about my wifi and host it myself..

[jaunty compass]

I want to connect a lobby, I didn't say that sorry

[cold latch]

wait so you're gonna run a lobby, proxy and main server off a 2 vCPU?

[jaunty compass]

No

I want to know if I can get something better for about $30 a month

if not I'll self host

[viral stone]

see hetzner auctions

[jaunty compass]

I have much better specs but horrible wifi

[cold latch]

https://www.hetzner.com/

$37 Euro (about usd or so) for something much better than what you're looking at

https://www.hetzner.com/dedicated-rootserver/matrix-ex and https://www.hetzner.com/dedicated-rootserver/matrix-ax are what I'm personally looking at for an entry level beta server for myself

the 13500 and 3600 are the two im considering, I came to the conclusion that I could run the 13500 better

there are 6 performance cores and like 8 efficiency cores on the 13500, use velocity and maybe your low performance lobby on those, then your main world on the 6 performance cores

[jaunty compass]

Would getting a shared CPU ruin the point of folia?

[inner swift]

Yes

[jaunty compass]

So dedicated only?

[viral stone]

Folia has sizable overheads

if you're looking at minimising budgets, just use paper

[jaunty compass]

I just wanted to know because there's a huge gap between 16$ and 37$

With dedicated

[cold latch]

I mean, it depends on how much performance matters to you, and player counts you expect?

if performance and player cap is super important (like, hoping for 80-100 players) then go for hetzner

[jaunty compass]

Not much, like 10 players.

[viral stone]

seriously, just use paper

[cold latch]

honestly just go grab a pebblehost thing

[inner swift]

Folia is pointless for your requirements

[jaunty compass]

Okay

[cold latch]

get some cheap off the shelf hosting

[jaunty compass]

Then I'll just use paper

[inner swift]

You'll be better off with Minecraft specific shared hosting

[cold latch]

^ yep for what you want I'd say pebble is the best

it's not perfect, but it's cheap and "good enough" for the price

[jaunty compass]

I'd rather use hetzner

[cold latch]

I mean it's probably overkill for 10 players

[jaunty compass]

Does pebblehost support velocity?

[cold latch]

I would assume you could set something up

join their support discord and make a ticket to ask some questions

they'll say if it'll work for you

[jaunty compass]

I also wanna get a bit more comfortable with the command line which is also why I wanna use hetzner

[inner swift]

If you absolutely must use a VPS/dedi/command liney hosting option at the cost of price per performance, look into bloom.host and pufferfish.host's VPSes

[jaunty compass]

Thank you

I'll check all of these options out

and see what works best

[verbal harness]

Ah please no not pebble avoid them at any cost they are a cash grab

If you are on a budget consider selfhosting or falixnodes

[cursive breach]

is it that bad? I've found them to be quite reliable over time

also what do y'all think of Contabo as a host

[cold latch]

Pebble is bad if you really need performance or a lot of players

but for 10 players or so it'd be fine

like I've had issues when trying to host 80-100 players

[livid crag]

ovh or hetzner if you want dedicated tbh. they are big so their price tend to be better.

[cursive breach]

It is indeed the budget option

Often I set up SMPs for medium sized groups of friends between 5-30 ppl who need the server up 24/7

Which is just nice for pebble

[cold latch]

budget is the right definition

and their higher tier stuff isn't worth it

[cursive breach]

AMD Ryzen 7 5800X - 8c/16t - 3.8 GHz/4.7 GHz
from ovh; is this really good enough for hosting a server with ~90 players spread out

[cold latch]

if you're talking about "game-2" that's stupidly expensive compared to hetzner

[cursive breach]

ah

[cold latch]

my pricing is in AUD at $120 which would be what, $80 usd or something

you could get a Ryzen 7 7700 with Hetzner for that

that is also a "sale" price

[inner swift]

Random performance

[cursive breach]

My web server and personal server is hosted with Contabo rn

It's a decent price for a host that offers locations in asia

€8+3 for 4vcpu 8gb ram in singapore

Uptime isn't guranteed though

[fair pewter]

I figured out how to build the 1.20.1 folia jar, but I cannot figure out how to clone the 1.20.2 dev one. Just keeps giving me the 1.20.1 jar, how can i clone the 1.20.2 version instead.

[pseudo ibex]

Git clone branch -b dev/1.20.2 https://github.com/PaperMC/Folia.git

[fair pewter]

im still confused, i dont understand what you mean by that

[fair pewter]

i got it now. Putting branch caused it to give me errors. removing it worked

[fair pewter]

Im getting this issue now when I try to build the jar. This didnt happen when I was building the 1.20.1 jar. I dont know how to do the possible solutions it says

[fair pewter]

its always failing at this part that didnt happen before with the previous 1.20.1 build

[arctic tapir]

update paperweight to 1.5.7

[fair pewter]

how can i do that

[viral stone]

in the gradle config for the project

[fair pewter]

now where is that "gradle config" because i literally have zero idea where iti s

[viral stone]

the build.gradle.kts file

[fair pewter]

I still have zero idea where that is

cannot find it

oh its inthe paperweight project. i found it, but I still dont know how to update

[viral stone]

wat

[fair pewter]

oh sorry i dont know how I missed it :l

just found it just now, sorry for the inconvenience

was able to build the 1.20.2 jar

didnt know i just had to edit the numbers in the file

[plush needle]

is folia compatible with datapacks? i dont see any mentions of it on the #readme in github

[livid crag]

datapack that dont rely on anything global stat will work. Though it will be very low prio if anything breaks.

[plush needle]

could u elaborate on what is "global stat"? thx!

im planning on running a OneBlock SMP (vanilla) with some people, so idk if that datapack is like compatible or smth

... so far, i aint getting a response. asking ChatGPT about it, global stat means anything to do with multiple regions in this case. I'm assuming this means it won't break!

[harsh yacht]

When you say "some people" that largely suggests less than 50 people or even 100 will be joining the smp on average meaning you dont exactly need Folia

You'd be fine with a paper/pufferfish server jar if so. Folia is experimental

[timid grotto]

global state* i presume. afaik, functions dont work, adding worlds should work, and tags/loot tables may or may not work

also player count doesnt really matter. if you have the hardware and your players will be spread out enough to create multiple regions (1.5k+ blocks), folia will still perform better

[finite hinge]

functions not working kills off most datapacks that "do things"

Well, really it kills them all, past that all a datapack can really do is make a new world

[timid grotto]

well they can add armor trims i think, not sure if that works on folia

probably other stuff im forgetting too. havent really been keeping up with datapack features

[daring nimbus]

worldgen works fine on Folia too. most of the datapack stuff that is basically an advanced config probably works

[jaunty compass]

Hey, I made a plugin that adds pumpkins called candies to the tops of mobs heads for holloween.

But when I kill the mob, the candies don't drop.

Wrong channel

[drowsy mountain]

hi, just installed folia via itzg/minecraft-server docker image. it works perfectly but i cannot send commands via rcon. keeps returning Error executing: help (null) for all commands (including help). if i send the commands directly via console it works fine. any suggestions?

version:

This server is running Folia version git-Folia-17 (MC: 1.20.1) (Implementing API version 1.20.1-R0.1-SNAPSHOT) (Git: edafbce)
You are running the latest version
Previous version: git-Paper-196 (MC: 1.20.1)

[viral coral]

wouldn't be surprised if rcon is broken

[drowsy mountain]

the rcon server or the rcon client?

[viral coral]

server

yeah that's definitely broken on folia

[drowsy mountain]

damn i already setup a web client for rcon. at least my server is more stable now. 😕

[viral coral]

why exactly are you running folia

[drowsy mountain]

just trying out things

[viral coral]

just keep in mind folia is not a great idea on less powerful hardware

& plugins have to be specifically compatible with it

[drowsy mountain]

i know but somehow it is more stable than paper

probably bc my single core sucks so bad

[viral coral]

consider going through the optimization guide on paper first

[tawdry gull]

Community contributed configuration guide for Paper: https://paper-chan.moe/paper-optimization

[drowsy mountain]

can i switch back to paper from folia later without too much changes?

[arctic tapir]

yes

[prime juniper]

Is it easier to move to folia from paper than from fabric?

[viral coral]

depends

if you have a bunch of fabric mods then yes

[prime juniper]

I do have a bunch of fabric mods

But I'm switching to paper

Because it has most of the plugins i need for moderation that do exactly the same thing as the fabric versions

And performance seems to be better

The only thing that is way worse is chunk loading and generation

But it's a sacrifice i'm willing to make given the fact that i can move to folia more easily later + I can also use skriptlang now + performance is better

For some reason it feels like fabric has gotten way worse in terms of performance lately

I can't get mspt to go under 5 even in a test server with 1 player

[scenic sky]

fabric aint the cause for that

[prime juniper]

While on paper with the same hardware I get about 1.2

[prime juniper]

of what

[scenic sky]

the performance becoming worse

[prime juniper]

I don't know

It just used to be better

Even with no mods or only performance mods

[scenic sky]

perhaps mods arent keeping up, just being ported to new versions without innovating

[prime juniper]

I can't fet mspt under 5

[tranquil epoch]

rcon? isn't this extremely unsecure?

[viral stone]

to expose to the web? yes; but some people do use it for internal tools, etc

[fallow stone]

whats the player chat event?

every one I see is deprecated

[viral stone]

Please actually read the javadocs

they often point you to nondeprecated variants

[tranquil epoch]

yeah I can probably just add back in rcon then

[golden mica]

hey leaf

The mob spawn have some problems

The number of mob spawn isn’t right

May you could check the code

[viral stone]

you would need to check the mob spawn limits as reported by the commands

folia is basically back to pure vanilla pre-per-player-limiting mob spawning logic which sucks for servers

[golden mica]

No

Never the same

I give you an example

If you per player is on and in bukkit.yml you let then vanilla

You will see so many mobs and any other animals

[viral stone]

per-player does not exist in folia

which means that the mob spawning logic has been rolled back to before paper and then mojang added that additional mechanism to try to control mob spawning more

ideally we would just rewrite mob spawning inside of paper to actually truly be per-player, but that comes with a lot of caveats

[golden mica]

But the fact is

[viral stone]

which was him removing per-player mob spawning properly?

[golden mica]

Even in bukkit.yml I set this number so low

Creature even higher than vanilla

[viral stone]

oh, nvm, no idea what he was doing there

[inner swift]

What are the actual mobcap command outputs

[viral stone]

as I said, you'd need to showcase mob counts

but, my heads far too spinny to play the game of requesting information

[golden mica]

Tomorrow I will show you the output

I can’t stop my produce server

If you let the bukkit.yml same as vanilla, the number of creature will make you suprice

[finite hinge]

This is so vague I feel like you're trolling

Why say surprised instead of saying it's too high or too low

[random garnet]

how do i fix these

[tacit tartan]

that's not a valid git command. Looks like you tried merging the clone, branch, and checkout commands all into one?

[random garnet]

how do i compile latest version of folia

[feral hazel]

Replace „branch“ with the github url

[random garnet]

okay let me try

[coarse prawn]

Folia discord get deleted?

[scenic sky]

there has never been a folia discord

[coarse prawn]

Yes it is

Bruh

[arctic tapir]

there’s never beeen one??

[scenic sky]

this is the folia discord

[buoyant tundra]

What's the current state of Folia? Is it stable by now?

[inner swift]

Still in dev

[tall arrow]

Hey guys I want to follow up this question. Does that mean it's lacking features compared to a paper server? Or that the multithread features intended to accomplish on folia are still in development?

I want to start a server for my community, and create custom plugin for it. Will folia lack anything that would affect vanilla Minecraft?

[arctic tapir]

data packs

certain commands

[tall arrow]

Oh so data packs are not implemented yet?

Okok that's what I meant

Thanks

[arctic tapir]

not every part of it iirc

teams aren’t a thing etc

[viral stone]

Please see the readme info, etc, etc; a lot of this stuff is documented

[clear kelp]

Is there a list of plugins that are supported on Folia?

[hexed ice]

you can filter plugins by whether they support folia on hangar

[merry grail]

#folia-dev 🙏

[fair merlin]

Please don't cross post.

[paper scroll]

What is the player-record eith folia yet?

[feral hazel]

1000 players ig

[paper scroll]

Thx

[tulip drum]

I how do I set up folia

I know that you have to build folia however as for running the server like with bat file how do you do that?

[feral hazel]

drag the built jar into a folder and run it. Same as with paper

[tulip drum]

I try it but then if does not work tell how can run though batch file

[feral hazel]

if you are on a windows system double click on the bat file

or what do you mean?

[tulip drum]

nvm

I was just building it wrong

[random garnet]

is it possible to play in a server with 8 cores running on folia for like 60-70 players

if someone tested it letme know

[feral hazel]

with 60-70 players yes. But more like 16 cores

[random garnet]

dont have 16 cores i was asking if it is possible to run a folia server with 60-70 players in 8cores

[daring nimbus]

the recommended minimum is 16 cores

With just 70 players, normal Paper should suffice, and it also doesn't need multiple cores that much

[feral hazel]

At least 16 cores are recommended. Anything under 16 cores not recommended and using paper makes more sense

[delicate lichen]

please help to me, I don't know how to expand Utilization, i use simple config file "java -Xms4G -Xmx4G -jar folia-paperclip-1.20.1-R0.1-SNAPSHOT-reobf.jar --nogui
pause", complex configuration file that I simply copied from someone "java -Xms4G -Xmx4G -XX:+UseG1GC -XX:+ParallelRefProcEnabled -XX:MaxGCPauseMillis=200 -XX:+UnlockExperimentalVMOptions -XX:+DisableExplicitGC -XX:+AlwaysPreTouch -XX:G1NewSizePercent=30 -XX:G1MaxNewSizePercent=40 -XX:G1HeapRegionSize=8M -XX:G1ReservePercent=20 -XX:G1HeapWastePercent=5 -XX:G1MixedGCCountTarget=4 -XX:InitiatingHeapOccupancyPercent=15 -XX:G1MixedGCLiveThresholdPercent=90 -XX:G1RSetUpdatingPauseTimePercent=5 -XX:SurvivorRatio=32 -XX:+PerfDisableSharedMem -XX:MaxTenuringThreshold=1 -Dusing.aikars.flags=https://mcflags.emc.gs -Daikars.new.flags=true -jar folia-paperclip-1.19.4-R0.1-SNAPSHOT-reobf3.jar --nogui
pause" I don’t understand how to set Utilization, make it large, for example not 100% but 200-400%, the characteristics of my PC i5 9300H, gtx 1660 ti, 16 RAM, 8x8 2666MHz, (I know that this is not a server, but I just want to test ) help me please

[arctic tapir]

not enoguh cores

[hexed ice]

you have 1 player online

[feral hazel]

16 cores are required as a minimum. And you have 4. Use paper

[arctic tapir]

also 1.19 is not supported

[delicate lichen]

But if you run it on a 16-core processor, will everything be automatically configured as needed? or does something need to be written down? and exactly 16 core (not threads?)

[viral stone]

Read the docs

[delicate lichen]

I read the documentation, but I don't have the opportunity to test on a 16 core PC

[viral stone]

The docs state how stuff is calculated last I knew

and how to tweak the thread counts available, etc

[delicate lichen]

I just want to test and not run a game server

[viral stone]

Basically, you're working with pre-release software of a highly technical nature in which you're expected to have some level of technical understanding

you can increase the max utilisation by tweaking a few settings, as per the docs

but, that's not magically gonna make that region which is shitting the bed that hard any faster

[delicate lichen]

I specifically loaded the thread with work to find out how other regions work, I just want to change Utilization 100% -> Utilization 200%

[daring nimbus]

are you on 1.19 by any chance? there was a bug causing regions to completely stall in 1.19

[viral stone]

Yes, and you can do that

iirc it was a setting or a system property

[tawdry gull]

Folia

Folia is a fork of Paper that adds multi-threaded region support. Many plugins will require updating to support Folia. There is no ETA for publicly available builds.

For more information:

• Readme
• FAQ
• Regionising logic
• Detailed overview
• Javadocs

Folia will:

• NOT be backported to older versions <1.19.4
• NOT be merged into Paper
• NOT be ported to Fabric nor Forge

Stay tuned to #announcements for any further info about releases.

'ETA' means 'Estimated Time of Arrival'!

[delicate lichen]

I intentionally created a load on the region

[delicate lichen]

I use a simple config file "java -Xms4G -Xmx4G -jar folia-paperclip-1.20.1-R0.1-SNAPSHOT-reobf3.jar --nogui"
pause", everything else is completely standard on the server, what do I need to write to change Utilization 100% -> 200%?

[viral stone]

that's not a config file

it's in the paper config files

idr the thing, read the docs

[delicate lichen]

I don’t understand, please, in 2 words, what’s wrong? 4c/8t?

[viral stone]

wat

[fierce knot]

https://docs.papermc.io/folia/faq#how-to-best-configure-folia

[livid crag]

If you cannot spend the effort to read a single page explaining everything you asked, you don’t deserve help from here.

[delicate lichen]

I found how to do this, is it really difficult to write “config -> paper-global.yml -> threaded-regions:”, I have no complaints, I just wrote, but thanks (and this is not written here)

[viral stone]

It is written in the bunch of documentations we tell people to read before using the software

[delicate lichen]

It's just not written in the folia documentation

[viral stone]

it is in the FAQ

[tacit tartan]

(it's likewise relatively trivial for us to distribute folia builds, but we again don't because we want there to be a higher barrier of entry due to the early beta state of the software - we don't want random users trying to use folia in production withouth knowing what they're getting into)

[viral stone]

Right in the section you wher elinked

[delicate lichen]

I’m not opening my server on folia right now, I’m still testing and studying

im my pc

[delicate lichen]

blind, didn't notice, thx

[delicate lichen]

how to find in config file "Netty IO"?

"chunk system io threads: ~3 per 200-300 players" -> find

chunk system workers if pre-generated, ~2 per 200-300 players -> find

(under global config, threaded-regions.threads) -> find

[finite hinge]

I think that one is in spigot.yml

[delicate lichen]

spigot.yml -> settings -> netty-threads? thx

[queen olive]

Asking out of sheer curiosity. Is the reason folia is only built from source and not provided as a jar, is as a softlock for the requisite tech skills? In other words, to prevent a bunch of idiots from going "I swapped my paper jar for folia jar and everything broke, please fix it for me"?

Oh nvm literally like 5 messages above lol #folia-help message

As well as bottom pin strongly suggests as much

[bold osprey]

yeah, it's still beta and should be used only by developers, it's not recommended to use on production (or can do as we do, only for servers that will live a only few days, like for a build contest or something similar, even if something will break it won't be too severe, if the contest is a pvp contest then better use paper, as a sudden crash can give a really unpleasant experience)

[finite hinge]

I mean, it's not known to be unsuitable for production 😛

But the whole project is very DIY and if it breaks you get to keep both pieces and is likely to stay there

So if you can't figure out the basics of building and configuring it...

This channel wasn't even supposed to exist but we were worried without it #folia-dev would get used by people trying to just run it

[bold osprey]

at least it was known for that, at the last test run the chunk sent error crashed the server a lot of times (and were other crashes that we were just missing), sometimes up to 5 times per hour, but it was on 1.19.4 so things may have changed

so, if it's not something that can tolerate some crashes, like something related to pvp, it's really bad to run it on folia

[deft zephyr]

does world guard and world edit have folia support yet?

[feral hazel]

WorldGuard and WorldEdit do not.
FastAsyncWorldEdit is currently working on Folia support: https://github.com/IntellectualSites/FastAsyncWorldEdit/tree/feature/folia

[pearl vine]

Hey, i got a problem in Folia, where the distance of mobs triggered by a player is waaaaay too low and i dont know why and cant find any matching config.
For example: Phantoms dont attack players because they are simply too far up in the sky to get aggressive towards the player or the enderdragon never going to rest on his pedestral in the middle because it acts neutral to the player due to its distance, same with enderman, they get only aggressive when you stare them in the face AND you stand right in front of them.

[inner swift]

entity activation range

But make sure you're fully up to date

[pearl vine]

i am on the newest current version, thanks

hmm

entity activation range seems to be correct

[cinder timber]

Does Folia works on 1.20.2?

Compiled from github, but seems it works on 1.20.1

[viral stone]

there is a dev branch

[cinder timber]

Yep

Compiled it the first time to be honest and idk what is wrong

Seems that I compiled it with the last patch, but it works on 1.20.2

Does it works if I just use gh repo clone PaperMC/Folia from 1.20.2 branch?

[viral stone]

No, that's not how that works

you need to checkout that branch

[cinder timber]

Thanks, now it compiled as 1.20.2

[minor plinth]

can i join a papermc server with a cracked launcher

[inner swift]

This is not supported here

[minor plinth]

but can i?

[inner swift]

That's on you to find out, we won't help you with that

[viral coral]

no

[arctic tapir]

literally in themessage above lol

also no

[viral coral]

it's called bukkit

[arctic tapir]

insanely hard and stupid

[viral coral]

folia already breaks bukkit plugins to some degree

attempting to add fabric or forge support seems like a waste of time

[viral stone]

Handling something as invasive as folia with stuff like mixins would be arse

you can also run folia with something like ignite

[viral coral]

even if folia existed for something like forge

it'd be stupidly expensive to run at scale

modpacks are heavy

not to mention you'd have to make sure every mod is compatible with folia's changes

you should not have too many performance issues with 10 players lol

[viral stone]

There have been various mod attempts to parallelise the tick loop in forge

[viral coral]

512gb ram & 32 cores sounds like bad hardware though

[viral stone]

they all generally end up dying a cold miserable death

[viral coral]

java isn't the problem

[viral stone]

nothing to do with java

concurrency and highly globalised state is not a good combination

[viral coral]

the community is not going to be waiting on major changes to apis that are like 10 years old at this point

[viral stone]

assuming you mean event driven, theres already threaded re-impls of the MC server which do that

and are generally missing 90% of the features, because gl writing predicable game logic without a tick loop

[viral coral]

was about to say the caveat being that they're written from the ground up instead of based off of vanilla

meaning you miss basically everything for a normal SMP playthrough

[buoyant tundra]

Considering that Folia benefits from having lots of cores, would it be smart to get an ARM server that typically have more cores?

[scenic sky]

how well that works hasnt been really tested

[paper siren]

Java runs fine on ARM, and also there are many different GCs with different characteristics.

[novel lodge]

how is ARM not mature yet

it is been mature for more than a decade now, just look at phones

[viral coral]

only really been relevant for server usage in the last few years

and now desktop usage with apple silicon

[manic basin]

How to setup folia
I used amd epyc 64vcore

I want used full core to folia for performance

Pls don't say go back to papermc
I have plan to make smp server

[arctic tapir]

how far away will your players be from each other

[manic basin]

I don't know too

But I need world loading performance, fast.

[arctic tapir]

if your players are close to each other you’re better off using paper

also don’t run this on a vps/vds or something like thzt

[manic basin]

No

The players are far apart.

Full SMP

I'm outside the house

This is my server.

[tranquil epoch]

is it pre-generated?

[fair merlin]

Are you using a VM on that CPU? Or a dedicated server?

[viral stone]

it's a VM

[fair merlin]

That's gonna be rough.

[viral coral]

it's an azure vm

probably leeches off of free credit

especially considering there's a desktop environment on it

[dense pivot]

does folia not play well at all with vms

[viral stone]

I mean, folia adds a chunky overhead

combine that with the overheads of KVM

potentially noisy neighbours, etc, etc

[buoyant tundra]

How would I do with a beefy ARM server from Hetzner?

Or rather still x86?

[viral stone]

like, using a VPS is generally not the ballmark for something like folia

We've only tested x86

arm is generally a little less mature and niche in terms of servers

[buoyant tundra]

But in theory, the ARM cores do count?

[viral stone]

well, yes

a core is a core

as for how well that core performs and the underlying architecture, etc, etc

[buoyant tundra]

🤷

Good to know then

[viral stone]

folia just cares about having a sane number of pipelines able to jam work down

HT is a ballache because it can eat generally around 30% of the performance iirc was the figure in suboptimal cases

(something I'd imagine MC would induce)

as for arm, it's generally gonna depend on the CPUs architecture

[fair merlin]

You'd have to test it, but it probably won't be as fast. No one's tried a high core ARM dedicated CPU yet AFAIK

Minecraft wants high speed cores. Folia wants high speed cores and a lot of them.

[buoyant tundra]

Well, I don't think I'll be the first to try. But thanks for letting me know!

[finite hinge]

If you can spread people out enough lots of slower cores might be alright. Basically take whatever 3-8 of those cores can support on Paper and scale it up based on how many cores you actually have

Assuming you can spread people out optimally

[manic basin]

Not azure

AWS, AZURE have host

[manic basin]

Oh sorry

But i not used azure

[finite hinge]

If it's not azure someone is ripping you off reselling azure stuff or failed pretty hard at installing things...

[viral coral]

you're definitely running something sketchy if you're running the azure kernel and have hardware like that

only to run a desktop environment

[manic basin]

But I have access to all the resources. and can access root

[viral stone]

yes, you have access to all the resources assigned to your VPS

[manic basin]

I used folia now & everything is normal

[viral coral]

no one is going to give you a 7502p + 128gb ram for cheap without using some stolen azure / aws account

is the point that i'm trying to make here

[inner swift]

Well, you can just compile it ¯_(ツ)_/¯

[manic basin]

i open server now

[inner swift]

People are just telling you it that there's something off with this and likely not a good idea, but you're free to use it

[manic basin]

but this server not have ipv4
i used ngrok & used my server (volocity) to connect

[viral coral]

that makes it even sketchier

[manic basin]

You can recommend config for this?

[manic basin]

.

[fair merlin]

You don't want to be using a VM for Folia or Paper.

Too slow.

[manic basin]

spigotmc & bukkit very slow

[viral stone]

you're running a CPU optimised for hosting web servers, not gaming

on a VPS, at that

[manic basin]

Folia for me good cpu used 11% eltra gen maps

[manic basin]

I don't have enough money for that.

I got this for an affordable price.

[viral coral]

because it's probably stolen

[manic basin]

I don't care about that.

I rather think it is safe.

[viral stone]

either way, I believe this discussion has generally run its course

[manic basin]

It has limitations with only 64 GB storage spaces

[manic basin]

Ok sorry

[finite hinge]

btw Paper generates chunks just as fast as Folia, afaik

[manic basin]

Ummm I came to folia because it multithread my vm clock speed only 2.49Ghz not 4Ghz up

[dark path]

I can't imagine you couldn't just host your SMP on a traditional MC server hosting site just using Paper. Folia is best afaik for when you need hundreds of players all far apart from each other, SMPs usually (in the traditional sense) have people close-ish together for interaction.

I could imagine anarchy servers would benefit a lot from Folia, but a regular SMP? Not so sure

[viral coral]

smps can work fine if you set them up in a way that it spreads out the players

[dark path]

Then again, I'm no expert

[dark path]

That's why I said the "SMPs usually have people close-ish together" part

Wasn't meaning to imply SMPs wouldn't work just based on them being an SMP

[finite hinge]

If you have a PvE server where people naturally come together in groups to make towns or whatever then you just have to ensure each of those are far enough apart

You don't get the full usage you would from something like 2b2t where each player may end up in their own region but you still have each town in one so farms and such are isolated

cleanCache then applyPatches with --no-build-cache

[royal swallow]

Do you think I could benefit of going over to Folia?
https://karta.agoniamc.eu/ (check map how players are located)

Right now is a pretty dumb time tho, since it's a swedish server and we are around 30-70 players online during days. And people have big farms and stuff which we had to nerf the shit out of to save performence and keep up good TPS. We are also a serious server with a good income, so we can afford a even better dedicated machine with more cores/threads for Folia usage.

[daring nimbus]

it will make sense if the players are very spread out, and all your plugins work with it (or you can afford to modify them to make them work). Your map seems pretty large, so as long as players are actually spread through the world it might make sense

[slender anvil]

It depends on your cpu

[fallow stone]

wow

[finite hinge]

iirc the only reason it should fail there is due to git not being setup

[silver sierra]

if it was that it would usually fail on a later step

libraries failing to download and git clone failing kind of point to a flaky connection

[viral stone]

I do wish our tooling would be more "happy" to dump command feedback out when shit goes sideways, etc

[modern plume]

Can i run folia on this?
