Can't really guarantee that there'll exist a good solution for this kind of setup, Spark has a Folia branch you can compile to try and get some more details

fair merlin
#

That's the kind of behavior you'll see with underpowered resources. Not enough cores means it's going to choke out, basically.

finite hinge
#

I wonder if it could hit 100% if GC threads starved it from actually getting any CPU time

#

Or chunk IO threads, etc

tired snow
#

I'm building a server, would the host benefit from high caches or would simply having as many cores as possible get the best results for a large folia player base?

lofty magnet
#

what do you mean by "high caches"? CPU caches? And yes, core count plays a significant role if you can actually manage to spread your players into lots of regions

tired snow
#

large caches, sorry

viral stone
#

I don't think anybody has generally cared to bother benchmarking how much CPU caches matter for MC, especially given the whole "ticking an object with a few gigs of memory" type stuff and the game not being catered to take advantage of locality, etc

tired snow
#

density it is then

umbral tusk
#

how well will folia run on a AMD 7950x

finite hinge
#

It'll run

west lily
#

probably wont crash if you put more than 20 people on it

finite hinge
#

I think that's basically the minimum CPU to use if want to ensure it'll actually be an improvement over Paper

#

Assuming you can spread your players over large enough area or over enough worlds

west lily
#

I dont even know how much of a difference the higher clocks will make; might just be worth it to run a few paper instances or choose a cheaper 16 core xeon

finite hinge
#

Well, each region still wants all the single core perf you can provide

west lily
#

oh thats interesting

finite hinge
#

But if you can get your regions small enough (like 20 players or less in each) then you can get away with a slower CPU that has more cores

west lily
#

that'll be good for something like a minigames server id imagine

#

spread the maps out a bunch

finite hinge
#

Think of it like each Folia region is a Paper server plus some overhead for the threading minus some overhead because they're all sharing IO and GC threads

west lily
#

ah

#

that's actually quite incredible

finite hinge
#

Unfortunately the plus overhead is on single core perf and the minus is on multicore so...

west lily
#

i wonder how GC runs on all that RAM

finite hinge
#

Modern JDK G1GC, ZGC, or Shenandoah chews through dozens of gigabytes of heap with no problem

#

They aren't O(1) with respect to heap size but it's some logarithm that makes the overhead scale very slowly

#

Well, that's mainly true for ZGC and Shenandoah and they also have such a large fixed overhead that they don't make sense for anything less than like 10GB unless you have CPU cores sitting idle and want as little GC pausing as possible

umbral tusk
#

so I would say so

tranquil epoch
#

yeah you should be able to handle quite a few players

Hey!

Is Folia stable?

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:

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'!
subtle lion
#

I didn't really understand. I was asking is it stable or not?

#

I don't think this message answers my question

jaunty atlas
#

How stable do you want it to be? It works, but it’s not so stable/finished that a public release has been made

viral stone
#

I mean, we're still not offering publically available builds, soooo

oblique topaz
#

Could someone explain why intel’s efficiency cores don’t work well with Folia? I read that 2 e-cores roughly equals 1 p-core, so an i9-14900K (8P+16E) should have the equivalent of 16 cores with more flexibility to place them where needed? Could they potentially work well in the future?

Also a question for Folia or Paper, I’m wondering if e-cores could be prioritized when 0 players are online to reduce power consumption.

livid crag
#

You can’t decide what thread uses score

timid grotto
#

so with that cpu, youd have 16 good threads (the p-cores), and 32 "bad" threads

oblique topaz
#

Ohhhhk thank you!

finite hinge
#

An e core is probably good for a couple people though

#

So if you were doing a skyislands server and for some reason wanted to make it a single giant server instead of using velocity they might actually work out

#

Of course you'd have a player count limit of like 100...

humble mesa
#

Is there an eta for folia release? I don't mean an official release date, just a ballpark guess.

fair merlin
humble mesa
#

thats fair, its hard to guess anything like that anyway

fair merlin
#

Folia's still in active development. You can use it, but you kind of need to know what your'e doing and be able to get plugins working properly.

To be honest there's a good chance it'll be a very long time before it's "mainstream released" like that.

#

Because plugin compatibility is very particular.

humble mesa
#

Fair enough. thanks for the update

fair merlin
#

But you can build it now and run it if you want to update stuff, run a server, experiment, etc.

#

A bunch of people are running it in production.

#

Depends a lot on what your use case is.

humble mesa
#

Yeah, i have a semi-anarchy server that averages around 25 players. This would be a game changer, so i am just exited. haha

#

we may run a test server useing folia, but it would be nice to have a few more bugs worked out first

fair merlin
#

If they players are generally pretty spread out past 1500 blocks and you have the server resources to run it, definitely worth a shot. You'd have to look at the open bugs and see if any of the existing bugs are actually showstoppers for you.

#

Most of the issues are plugin compatibility.

humble mesa
#

yeah, we already use a Ryzen 7900x, it would be easy to switch to a 7950x

humble mesa
fair merlin
#

You can definitely spin up a test instance on less cores and check for plugins working and stuff and test with 1-2 players.

humble mesa
#

alright. We might do that just to see how it goes

#

does folia require any funding, or is everything covered atm?

fair merlin
#

Donating through Github or Open Collective is always welcome.

humble mesa

I mean you could ask in helpchat, but like seriously that'd be a pretty big project I don't think anyone would actually want to hastle with it

plus unless it was Leaf doing it, they'd prolly find some way to fuck it up

Leaf will never do this

plus Folia breaks tons of plugins

it will also break tons of mods

void elbow

yes i know

foggy blaze

if you did this, literally half your mods would explode of not all of them

void elbow
#

But I only use 2 mods, I can fix them

foggy blaze

that's not as bad at least

foggy blaze
# void elbow Leaf will never do this

yeah, thats my point. Leaf would prolly be the only one who could do it without screwing it up and they certainly aren't so it's not even worth trying to get done.

scenic sky
#

if you only have 2 mods i cant imagine it being impossible to replicate with plugins

fair merlin
# void elbow Leaf will never do this

You really don't want mods working together with plugins. If you only have two mods you should find someone to rewrite them as plugins, which would be FAR easier than finding someone to cobble together mod support in Folia.

void elbow
#

and Quark

fair merlin
# void elbow IC2 Classic

Not sure what those are. Like I said, you'd be better off finding someone who can re-write those as plugins, or find existing plugins to cover that gap.

#

I would not even remotely try to use Paper or a Paper fork with mods.

feral grotto
#

why it called folia

gentle raven
#

i think folia is latin for leaf and since spottedleaf created it it was called that i guess

ill take it

cause folia is tinfoil in polish

and other languages

gentle raven

lol

folio is what you use to contain a bunch of papers

Is folia sufficend stable for a in production server?

gentle raven

i mean it depends on what kind of server you have

uneven walrus
inner swift
#

There are not many "common plugins" in Folia

gentle raven
#

well i am unsure of the current state of this but afaik plugins won't load unless allowed in plugin.yml so you will have to edit that

inner swift
#

The huge majority of plugins need a rewrite, so changing the plugin.yml will not be enough to make them work

Not originally, it was later modified for Folia, has been so for approximately a year.

Yeah probably need to just update it then

so you could use datapacks

you just won't be able to unload the world/load them later than server startup

Hi, our team was using folia for hosting an SMP factions server for players with peaks up 100-200 players at the same time. But we are slowly realizing that folia is causing some problems and it is getting harder to came up with work arounds. Is there any other way to host a server that will provide a reasonable performance to players than folia?

jagged ether
#

We don't make server software other than Paper and Folia

viral stone
#

I mean, there is a reason why we're not recommending folia for production yet, and, generally, no, hosting large numbers of players on a server without basically hampering players is generally not too much of a thing

#

forks exist which can help shave off time here and there but, no magical solutions here

#

(we, ofc, do not provide support for, nor recommend any forks)

naive fable
#

If you report the problems they will probably get fixed eventually

timid grotto
#

i could be wrong, but afaik folia doesnt have many bugs that a player would notice just playing in survival. most issues come from missing some vanilla commands (notably /worldborder) or (lack of) plugin support

#

it is VM, Linux, I am not sure about the CPU, but we have at least 16 cores

feral hazel
#

A VM is not a good hardware for folia!

#

you should have full hardware access

fair merlin
#

Yeah if you're on a VM and aren't sure about the CPU then you aren't meeting the hardware requirements.

finite hinge
#

A VM is fine, it just usually doesn't make sense for folia as I doubt you have a server with enough cores to make it worth splitting it up like that

#

64 core server? Sure, use VMs to split it up. 16 core server? That's a dedicated folia server, no need for a VM when it uses 100% of the machine

fair merlin
#

VMs are fine for some stuff. Just not great for Minecraft in general and not recommended for Folia.

finite hinge
#

VMs are fine for Minecraft in general

#

CPU overhead for a VM is basically 0 and Minecraft isn't IO bound

#

Unless your VM is pretending to be some CPU from 2012 to make it easy to migrate onto a wide range of machine types/ages, then the JVM will avoid some optimizations with newer SSE and AVX stuff. Although I don't know that MC does anything that would really benefit from any of that either

#

The only time VMs are no good for Minecraft is if you're oversubscribing (telling 4 VMs they all have 4 cores when your host only has 8) but that's true for running on bare metal or in containers too

fair merlin
#

I think you'd be hard pressed to find many hosts in Minecraft that aren't over-allocated.

finite hinge
#

Sure but who is running folia on shared hosting?

fair merlin
#

Back to my original point: Don't use Folia on a VM.

#

And make sure the hardware you're using meets the recommended requirements.

finite hinge
#

I suppose this is just one of those "if you know what I said is wrong you don't need this advice" things

I don't know how to compile folia

arctic tapir

then folia is not for you

limpid fable

is it impossible to use player.getBedSpawnLocation() on Folia? whatever I try I get a off-main scheduler error.
Which scheduler would be the correct one, to get the main thread scheduler?

subtle oriole

player.getScheduler() I think

limpid fable
#

I tried using that (or well, scheduler.runAtEntity(player, () -> { var loc = player.getBedSpawnLocation(); System.out.println(loc.toString()); }) from FoliaLib)

#

but it returns the same error

#

looking at the Folia code for tick thread checking refers to the chunkX and chunkZ, which I don't even know how to get since that's exactly what I want to figure out 😂

subtle oriole
limpid fable

alright, thank you

but we got past the thread check

timid grotto
finite hinge
#

Sounds like a bug, it should be the entity scheduler

#

The tree gen error happens when you try to use the async or global scheduler for something that is supposed to be in a region-specific one

#

And the entity schedulers are basically region-specific ones that keep in sync with the region of the entity

We are for most things, but Folia is intentionally made difficult to use due to the instability and potential bugs of it.

pastel musk
#

just curious, why is it made difficult?

tacit tartan
#

It's still a quite experimental software. There's several systems that haven't been implemented yet, plugins have to explicitly support folia, and it's likely there's still some serious bugs that haven't been found yet. By gating access behind the knowledge of how to build folia, it's assumed you would then also possess the knowledge of the risks you're taking, how to update any custom plugins to work with it, and just in general you know what you're doing

Folia is a Paper fork adding regionalized multithreading to the server to support large amounts of players playing on the same server without the need for BungeeCord.

It works by grouping nearby chunks to form an "independent region."

Each independent region has its own tick loop, which is ticked at the regular Minecraft tick rate (20 TPS). T...

Oh

i use windows for it aswell

just disable the path length limit or put it at head of c

Then how should I proceed after moving folia tone drive

follow the build instructions on the paper repo

I have an EPYC 7B13 server with 128c256T and System is Windows Server 2022 How can I set JVM startup parameters to make the best use of Folia,I want Folia make full use of my CPU core

But the server looks very sluggish

solid mirage
#

No, this is a physical machine

#

but the system is windows server 22

#

It has 128cores and 256Thread

fair merlin
#

Ah gotcha. I don’t know that CPU as well.

I would really recommend running in Windows, for starter

solid mirage
#

I am a dual CPU server. one cpu 64cores and double 128cores

fair merlin
#

Oh yeah. NUMA is not supported.

#

You probably want to disable a CPU.

solid mirage
#

Do you mean that I should turn off NUMA to improve Folia performance?

#

I dont want to disable a CPU,should i disable it?

fair merlin
#

I would.

solid mirage
#

ok i would try to turn of numa soon

solid mirage
fair merlin
#

Yes, but Folia isn't designed for multiple CPUs

fair merlin
#

Not sure if/when NUMA will be supported.

viral stone
#

Folia uses more cores, but

  1. It's still ticking individual regions just like it would tick many other servers
  2. Java does not have support for NUMA awareness inside of applications, and that's an architectual issue that you would want to design an app for, not try to bodge into down the line
timid grotto
#

well its on 2 cpus, not 1. as discussed, that is a source of slowdowns

viral stone
#

10x, no; not unless you get some really bad luck I guess

solid mirage
#

ThankU very much !!! I found the plugin.

#

But It seems that folia use not more than 64 Thread? Whats the problem?

fierce knotBOT
solid mirage
#

When my Folia server is high stressed only CPU(Thread) 0~63 is full,others mostly Empty

image.png
#

but paper global threaded regions I set 200, so should i use linux to run folia?

#

netty io :32 work thread:30 io thread: 10

inner swift
#

You should use Linux to run large scale MC stuff

#

Well, how many loaded regions out of these 200 do you have?

solid mirage
#

my server have 300+ players and over 200 regions

#

simulation distance 4

inner swift
#

Looks about right then, region threads aren't guaranteed to be put in different CPU cores

solid mirage
#

Yes, a large number of regions cannot run on more CPU cores, so there is no other way besides replacing windows with the Linux system, right?

inner swift
#

Windows should be able to use more than 64, it's just not doing that because it feels like it doesn't need to

solid mirage
#

Sure,I have found that it is a plugin issue yet, but the funniest thing is that the plugin causing MSPT 1000 is Spark. I deleted the spark and then the server has never been stuck

bold osprey
solid mirage
#

Will the 64 thread limit problem be related to the memory channel? Epyc supports 8 channels, but currently I only setup 2 channels

solid mirage

very healthy

#

but in plugin, I get method Runtime.getRuntime().availableProcessors();,,,then it only return 64,,,,,,

bold osprey
#

it's perfect 20 tps

#

that means that 1 thread can tick several regions

okay when tommorow i got 300+ players and then i will give a screenshot to you

I wouldn’t run Windows for Folia and dual CPUs aren’t supported by Folia either.

Not sure what your server setup it but if it runs on your PC then it sounds like your server is the issue.

so exactly how should I use

WSL

livid crag
#

This isnt really a channel to teach you how computer / OS works

pastel musk
#

currently doing wsl --install

livid crag
#

his point is that if you do not have such knowledge, you should not be isung Folia because it requires way more knowledges to run because it is not released yet

#

Do you know that all plugins wont work with Folia?

pastel musk
#

and why would part of folia not get downloaded. I know all plugins fail

livid crag
#

are you running a server with zero plugin? or a very limited selection that has Folia support?

pastel musk
#

no plugins

#

why it is not released yet? just curious

livid crag
#

We do not want people with no deep knowledge of the eco system to run it and come here to complain that it doenst work.

#

or worse yet, go to plugin developers and demend them to provide support for Folia

fierce knotBOT
pastel musk

that is the exact error

craggy quail
# pastel musk I tried, but the errors still ocurr

The error isn’t to do with folia IMO. It’s not even related to Java. Looks like the Cygwin install is broken and git cannot function, so GitHub and gradle both fail.
You should probably

  1. follow whatever instructions the error messages are giving you
  2. search for those error messages if you are still having issues
  3. seek help from the Cygwin community
    Once you get your git/cygwin situation sorted:
  4. successfully build Paper from source. You should only start trying to get folia after you have a machine setup that can build Paper from source. Until then your issues are very specific to your setup, and the solutions will be documented in a bunch of places other than the folia channels.

Troubleshooting techniques you should try to focus on:

  1. Read error codes. They are there to help you solve problems. If you don’t understand every term in them, then look up the terms.
  2. work to understand the system. Often, you can figure out the solution to problems simply by reading up on the how the system you are working with works.
  3. isolate the problem. There are a bunch of tools that you are interacting with if you want to successfully build the jar file. Ideally, when you are testing a problem you only want to test the broken parts and keep things simple. In this case, you can test if your git command is broken by cloning any public repository from GitHub.

I have the same issue, generally with mob spawning...
if I disable per player spawn caps my metrics tell me that I'm usually at ~4k entities, but people report that there's nothing spawning
if I leave per player spawn caps enabled, I shoot up to 50k entities and the entire ocean is filled with squids and land is filled with animals... and I've already reduced mob limits so I have 0 clue what the actual issue is...

#

oh, and mob (like, bad guy) spawning is way too low for some reason

viral stone
#

there is an issue on the tracker, I think leaf was having issues reproducing it however

limpid fable
#

our mc project is open for registration if he wants it reproduced lul

I mean, that's useless

#

Cool, we can see that people are having issues, that's literally already documented on the issue tracker

#

We have no means of reproducing it in a controlled environment at the moment, however

what I've figured out: have ~30 people on a server, in the same region, with default mob spawning rules and be near an ocean

the ocean will entirely fill with squids and fish in a matter of minutes

then document that on the issue tracker

could you link me the issue?

Hi.

Sorry if this is a stupid question but i have been coding with bukkit/spigot/paper for like 10 years now so ud THINK i know what im doing but idk. What OS do you recommend for folia as I plan to buy a local machine to run a dev server till a release in 6/7 months. Also is there any documentation on how to build it or code with it? If this has been answered else where linking it is fine but i didnt see it tyyy <3 (PLEASE @ ME WITH REPLY)

#

Also another question thats a bit more generic, when i locally hosted servers in the past people in the UK would get same ping as if i hosted it with a company but when i do it local people elsewhere (in the US for eg) they get WAY better ping from a uk hosting company (compared to local) is there any glaring reasons why and is there any sort of tech i can do to help it? If local hosting was possible for release id love to go down the server rack route

Folia only potentially makes sense for you if you have hundreds of players

If you have that you should either be milking your whales with stupid microtransations or have some devs in the community that help run the server

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:

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'!

Folia plugin support is still nascent.

You may want to make sure there are plugins that support what you need, along with having enough system requirements and the correct use case to use Folia to begin with.

I use 10000x10000 worldborder, and Folia works better than Paper for my project, the only thing that is poorly optimized in folia is the spawning of mobs, they cannot be properly limited and there are some bugs with "triggered mobs" and mob-spawning

Hello,
I am fairly new to plugin development and converted my Plugin (just for some friends) to work with folia (it was straight forward). But now I am stuck at the point of changing the time with world.setTime(0). It tells me that is it not globally possible to change time.
Then I tried to run the command time set day as the server via plugin.getServer().dispatchCommand(plugin.getServer().getConsoleSender(), "time set day");. But it gives me an error that is is asynchronous an thus not working.

I intentionally do not share the error log, because I think I am at a dead end either way. Is there a know, yet simple way of changing the time/skip night. (It does not need to be efficient)

Thanks :)

"just for some friends" sounds like paper would be better, but theres a "global" region that you probably need to use for that

hi ! I have a question, folia is use for server with a lot of CPU thread ? for a better multi-threading ?

#

I have dual Intel® Xeon® CPU E5-2689 with a total of 32 thread at 2.60 Ghz

sudden tusk
#

I mean, already answered that 😂

It's for wanting hundreds on one server in specific setups. Needs ridiculously powerful CPU.

sudden tusk
humble raft
#

I want to test it but I don't understand how to compile that

#

when I test to compile that I have this error :

image.png
viral stone
#

first step is to clone the repo

humble raft
#

yes I do that with Github Desktop

#

and I have this error when I do gradlew.bat applyPatch

viral stone
#

other than that, try a shorter path, i guess

humble raft
#

oh thank's that work x)

#

I have a question can I compile that on my windows computer and after copy that on my server ?

viral stone
#

if you mean, can you copy the compiled jar, yes

#

if you mean, can you copy the source folder to a server, generally a bad idea

humble raft
#

ok thank's

#

with folia I can use all standard plugins ?

finite hinge
#

If your players aren't really spread out folia won't do anything for you

#

No, Folia is not compatible with any Spigot/Paper plugins

#

Some plugins support both but they have to explicitly support Folia

humble raft
#

ok folia is good for faction server or survival server ?

finite hinge
#

It can be, yeah, so long as your factions are very spread out

#

Like more than 1500 blocks from each other, the more the better

humble raft
#

ok thank's 🙂

inner swift
#

Your specific CPU will not be suitable for this kind of server, by the way

finite hinge
#

If any players are within 1500 blocks of each other they're in the same region, that means if A is 1200 blocks from B, B is 1200 blocks from C, and A is 2400 blocks from C they're in a single region because there is no large enough gap between them to get a split

humble raft
finite hinge
#

Well, it's borderline

#

I'd worry the CPU is just bad for MC no matter what

inner swift
#

The single threaded perf of that CPU is really low, it'll struggle if a group decides to get near each other which tends to happen sometimes

#

I'd worry that it'd choke on a particularly heavy isolated player's base, as well

viral stone
#

at the end of the day, each region is basically a small MC server with some small amount of overhead to manage that

humble raft
#

what is the max of CPU thread I can use on folia ?

viral stone
#

you still need a CPU capable of handing that

#

there is no max

#

just, aspects like crossing silicon is slow

humble raft
#

oh ok

sudden tusk
mystic zenith
#

Sounds like this would be better served by a standard Paper server (assuming you don’t have a playerbase already and need the grunt performance + have the money to employ devs)

finite hinge
#

Most servers are better off with Paper

livid crag
#

Most sane server kept player max around 60 and make extra servers

calm fable
#

ive got a rather decently largish server, that im trying to optimize to hit the 200+ player mark, what flags should i be using on the start script and what are some kernel tweaks i should put in place, if anyone knows, any help is greatly appreciated

#

also is there a way to tell folia to be liberal on the region threads instead of making regions so large

fair merlin
#

The regions are dynamic, so no.

viral stone
#

the region size requirements are hardcoded due to vanilla behavioral concerns and performance

calm fable
#

my current issues is theres a lot of people near spawn, sim distance is 16 and 1 core gets a bit loaded at times and was wondering how to alleviate taht

viral stone
#

there is no way to aliviate that which isn't basically having multiple spawns

calm fable
#

ok cool, is there any known recommended startup flags and options for java for best optimization?

viral stone
#

No

#

We generally just point to aikars flags as a general good basis

calm fable
calm fable
#

so for anyone who asks in the future, i set these settings and it helped the server with performance noticeabley ```echo kernel.pid_max = 4194303 >> /etc/sysctl.conf # not really needed but good to have
echo net.ipv4.netfilter.ip_conntrack_max = 196608 >> /etc/sysctl.conf
echo net.netfilter.nf_conntrack_max = 1048576 >> /etc/sysctl.conf
echo net.core.rmem_max = 65536000 >> /etc/sysctl.conf
echo net.core.wmem_max = 65536000 >> /etc/sysctl.conf
echo net.core.wmem_default = 262144 >> /etc/sysctl.conf
echo net.core.rmem_default = 262144 >> /etc/sysctl.conf
echo net.ipv4.tcp_rmem = '32768 87380 65536000' >> /etc/sysctl.conf
echo net.ipv4.tcp_wmem = '32768 87380 65536000' >> /etc/sysctl.conf
echo net.core.netdev_max_backlog = 30000 >> /etc/sysctl.conf
echo net.ipv4.tcp_congestion_control = htcp >> /etc/sysctl.conf
echo net.ipv4.conf.all.rp_filter = 2 >> /etc/sysctl.conf
echo vm.swappiness = 0 >> /etc/sysctl.conf
echo net.ipv4.tcp_mtu_probing=1 >> /etc/sysctl.conf #only if using jumbo frames.

viral coral
#

that seems very doubtful

#

seems more like something that would be the result of "optimized sysctl parameters for performance" on google, practically none of these have anything to do with server performance

balmy meadow
#

idk much about linux kernel n shit, but yeah it's mostly all network related

viral coral
#

it's very likely to be more of a placebo than actual noticable performance improvements

fair belfry
#

why would you set the max pid to one below the default...

scenic sky
#

if there was a meaningful way to get more performance without impacting anything important, it would probably be default

#

this shits been tuned for years

timid grotto
viral coral
fair belfry
#

i guess its a distro thing

#

i checked on arch and ubuntu 23.10 and its both 4194304

viral coral
#

distros changing it to 4194304 is nice but yeah the default is still 32768

hey i got a question about folia.
on github folia recomends the cpu to have at least 16 cores but what are the downsites on running it on a 12 core 24 thread cpu?

fair merlin
#

It'll either run slower than Paper or it'll run so slow it crashes. Depending on the use case.

#

Folia isn't for everyone. It has a lot of specific scenarios in mind.

prime juniper
#

ok thanks

#

its for an anarchy server

#

i plan on buying a 16 or 18 core xeon next year

#

it currently runs on paper on a 6 core 2.6GHz WM

#

well thanks for the tip ill be looking for e5-2698 v3 or 99

prime juniper
#

ye i can just test folia on diferent hardware and see what it does

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:

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'!

fair merlin
#

For now we stick with our recommendations. But I don’t think it’s smart to tell people to use NUMA without warning them first about the possibility of large unexpected issues.

If it runs on fewer cores as a test, sure. But multiple CPUs are definitely unsupported and an unknown quantity.

#

Would much rather be cautious with people so they don’t run have issues

#

If they want to take the risk then at least they are informed.

finite hinge
#

4 cores or less, I bet it'll be slower 100% of the time. 8 cores or less, there might be cases where it's an improvement but they'll be niche. Past that it depends

sly elm
#

there is some overhead which can't be ignored, may or may not be a bit exaggerated but the point is mostly not to try running folia if you do not have the hardware and means to support yourself on it

#

for the average server paper is going to be a good choice

calm fable
#

the box im running folia on a 5950x with 64gb of ram and twin 2tb nvme's in mirror, which is async mirroring to an iscsi volume from my nas. its a pretty good setup i think, folia running nicely

Players MUST be at least ~ 1500 blocks apart so server can create new regions.

about 9x6k @hybrid shore

your world?

dawn hawk
#

yes

hybrid shore
#

💀

dawn hawk
#

players are roughly evenly distributed

hybrid shore
#

¯_(ツ)_/¯

dawn hawk
#

they are more than 1500 blocks apart in many cases

#

there's 4 distinct islands, they're all 1500 blocks apart

hybrid shore
dawn hawk
hybrid shore
dawn hawk
hybrid shore
dawn hawk
#

well yeah, that's the issue

#

I haven't ran into that issue

hybrid shore
#

cuz players are too close to each other

dawn hawk
#

they're definitely not though, feel free to come and take a look

hybrid shore
#

Those "islands" how far apart they are

dawn hawk
#

roughly 2k apart

#

with borders, so players can't go into the spaces between them

naive fable
#

You included?

hybrid shore
hybrid shore
#

This is the issue

dawn hawk
#

so, what else can I do to troubleshoot this

#

during testing before this event, we didn't run into this issue

hybrid shore
dawn hawk
#

yes, we had 3500

#

peaked at around 6000 at one point

#

usually we use multipaper, but thought we'd give folia a fair shot

naive fable
#

"distinct groups" arent enought, there should be no players in between the regions

dawn hawk
#

there is no players between the regions

#

at all

#

as I say, I triple checked, in fact the plugin we wrote for the event teleports players out of the spaces between each region

hybrid shore
#

If a player from one island will come to the border of the island and second player from island that is near will come to the border too then regions will be as one.

#

That's probably what's happening to you

paper siren
#

I mean as you can see you have >400 players in a region

dawn hawk
#

I kicked players except for the two regions on opposite ends of the map

#

there's still 1 thread

#

I think there's something else interfering

paper siren
dawn hawk
#

oh yeah, but we need roughly 10x that

#

and the 10 day event just started today

#

youtubers have hit record, so I gotta fix this live somehow

naive fable
#

Do you have some kind of map with players`?

hybrid shore
#

red dots are players, if that happen then regions will merge into one

image.png
dawn hawk
#

I know how it works

dawn hawk
naive fable
#

What is the view distance?

dawn hawk
#

I have gone so far to turn off chunk generation and delete the region files between each team's area

#

currently, 6

naive fable
#

What is the event called?

hybrid shore
#

If I was you I would create island every ~ 5-10k to be 100% sure regions wouldn't be merged.

paper siren
#

as one region contains 24k chunks, players doesn't seem to be separated enough to allow the region to split

inner swift
#

1500 is pretty borderline, and actually might be below the minimum depending on your setup

dawn hawk
#

yeah the two groups remaining after I kicked everyone were roughly 5-6k apart

#

I'm almost certain it's nothing to do with regions merging together with that logic

#

I'm thinking it's likely something to do with another plugin we're running

#

perhaps grimac/viaversion would interfere somehow

#

or, it's just a misconfiguration that's snuck in

inner swift
#

Hm, I guess it could be a plugin

dawn hawk
#

that's what I was thinking too, but it's too late to trial it without, and the setup hasn't changed in any meaningful way since the tests

#

normally, we'd have a change freeze between testing and the event, but some config changes snuck in

#

where in the source is that 1500 value before they merge together, I'll rebuild folia to see if that logic holds up

naive fable
#

Not really

inner swift
#

That value is tightly coupled with the inner workings of the chunk system

dawn hawk
#

egh, so there's not really anything we can do other than hard cut to multipaper or something mid-event, this blows

naive fable
#

Move the islands further apart

dawn hawk
#

thing is, on day 8 I'll just have to put them back together again, so that's gonna be too much hassle

#

the borders are supposed to come down and the remaining people (roughly 500 or so) will be able to interact with each other

#

I know we can deal with that many people on a single thread, but for the next 8 days we were supposed to whitelist 10k more people

#

so unless i can just get someone to magically whip me up a plugin that will translate the coordinates in everyone's player data by a specified offset and move the regions on those two checkpoints, this just seems like a crazy workaround

finite hinge
#

Folia pretty eagerly merges regions (it has to choice, things would explode otherwise) but it doesn't split them back up as eagerly to avoid ping ponging

#

So once they're merged people have to be even further apart to get it to split again

dawn hawk
#

any suggestions how we can do that

#

we're locked into folia now

finite hinge
#

Restart the server, maybe

#

But next time someone manages to merge them you're stuck again

dawn hawk
#

wonderful lmao

tawdry gullBOT
#

⚠️ 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.

finite hinge
#

iirc you might be able to drop that to 5 with the cost just being extra locking but any lower and you run in to crashes

tranquil epoch
#

some basic math here is going to be very useful

#

at around 1500 blocks radius for each player means that they need (2*1500+1)^2=9 million blocks^2 of area

#

you have a world of 9000x6000 blocks, or 54 million blocks^2

#

this isn't even the right shift to adjust

#

it can't be adjusted either it will break the server

daring nimbus
#

easiest and safest might be simply moving the players further apart. and if you do it by just adding two empty regions inbetween

fair merlin
#

I mean if Leaf says “don’t do that” I think it’s best if we don’t recommend people do that.

#

Also a reminder that bot testing isn’t a great representation of real players.

#

There's still a difference between "don't do that" and "be wary".

livid crag
#

Done sorry leaf fixed it Clue

fierce knotBOT
tranquil epoch
#

the ticket shift grid size is critical as it determines the range of ticket levels that are usable

#

I would highly suggest trying to read the code that uses it rather than simply playing around with it

viral coral
#

should also be noted that there's a config option to change the region shift @dawn hawk

#

instead of manually patching it with the above

tranquil epoch
#

wont help him

#

still too small for the number of players he has

#

for 440 players you need a much larger world

#

I would suggest trying a 60,000x60,000 sized world

fair merlin
tranquil epoch
#

folia's current region recalculation logic is set to recalculate a region if 16% of its marked chunks are dead (i.e unloaded)

inner swift
#

To be fair, their situation read to me like they had 4 islands near the corners of the world, which should be their own 4 regions with all the player groups exclusively confined in each

fair merlin
#

And then said it probably won't help you and that he recommends you use a 60kx60k world or something.

Excuse me

When using the CDN proxy Folia (based on TCP load balancing), I found that I could not obtain the real IP address of the client (all were IP addresses of the node servers).I tried to enable the CDN's proxy-protocol-v2 protocol to let the server obtain the address, but it did not work. I also tried using the haproxy-detector plugin, but I am not sure if there are any solutions.

zero plugins, same issue, seems to be something to do with using a map from 1.20.2 @fair merlin @primal quail

#

fresh map it's fine

fair merlin
dawn hawk
# fair merlin Sounds like some data messed up in the map, or a datapack

no datapacks, map is totally fine before running it with a 1.20.4 jar; it throws that error on join only after running it on the 1.20.4 server, then if you run that same map on a 1.20.2 server again, the same error is shown on join

I have to restore from a backup from before the map ran with the 1.20.4 server for it to be joinable again

I can reliably replicate the issue without any plugins & default config

fair merlin
dawn hawk
fair merlin
#

So walk me through how you're making the map / able to reproduce it.

Without any plugins or datapacks, you create a world on which build/commit of 1.20.4?

Or are you creating it on 1.20.2 and then upgrading it on 1.20.4? When you upgrade are you using --forceUpgrade ? (Don't do this if so)
