#

Is folia on 1.20.4 right now?

primal oyster
rotund fossil
#

The dev guide is missing?

daring nimbus
#

No one has written anything there yet. The region logic and overview pages in the "Administration" section of the folia docs should give you a good overview of what changed compared to Paper though

primal oyster
#

Folia still lacks lots of important events calls that help plugins like player teleport, spawn location and others

#

Its not gonna have a full dev API guide like that

subtle fjord
#

Does Folia have built-in config to limit number of cpu/threads?

primal oyster
#

If you're talking about regions yes

#

it's on one of the paper config and section conrains the word region

#

But that is already limited by default

subtle fjord
#

thanks

#

given that save-all is not available - how to people currently make backups without completely putting the server offline?

#

though I suppose I could just sleep until gc kicked in

hexed ice
#

i've always just done it while it's running without using save all/off

#

at least, the server i used to do stuff for

subtle fjord
#

I mean good point, need to check rclone, my only worry is that I upload a corrupted chunk because a write just happened.

lofty magnet
#

shutdown -> backup -> start back up is always the safest

#

even on paper save-all off is no guarantee that nothing gets written πŸ‘€

#

err wait, save off and save-all flish I mean

#

or whatever that syntax is, vanilla commands always have been weird there xD

subtle fjord
#

other way:

save-all -> save-off -> backups -> save-on

lofty magnet
#

no

#

you have to turn it off first, otherwise it might start an auto-save again after running the save-all

subtle fjord
#

yah, I use inotify to wait until no more changes happen

#

so technically:

save-all -> save-off -> waitsilence -> backups -> save-on

lofty magnet
#

well, but just because no change happens at one time it doesn't mean that no change is still queued?

#

of course this is a really rare edge case but still Β―_(ツ)_/Β―

#

literally no reason to not turn off automatic saving first

subtle fjord
#

its waitsilence, I wait for a set time - not just once-off check

#

but agreed, I will switch it around then, did not know save-all is queue

lofty magnet
#

use save-all flush if you want to save everything as instantly as possible (basically all on the main thread)

#

(well on Paper, no idea how that part works on folia actually thonk)

#

also pretty sure that doesn't even affect non-chunk-data πŸ‘€

subtle fjord
#

it doesn't but that is fine

#

obvs best is to take offline or use zfs snapshots πŸ˜›

#

honestly I don't think I even need it for folia.. save-off/on is enough.. with waitsilence I just need to increase timeout, its not like chunks are kept long in memory

tranquil epoch
#

something to note about folia is that level data (i.e level.dat) is not saved until shutdown, as I didn't find a way to make that thread-safe

livid crag
#

better shut done server to backup... even on regular Paper despite it seemly safe phosdorime

subtle fjord
#

I am curious about regions: is there some type of limit on how small they can be? So could a region be 2x2 chunks even though bordering chunks are "connected" via redstone?

I suppose I am curious how "slow" can the cpu really be vs number of cores, or if single-thread performance is still important to avoid regions having a low tps

fair merlin
#

Single thread performance is still important.

#

But you also need mor cores.

#

We still recommend 16 cores/32 threads, but you might be able to get away with less. It really depends on the setup.

#

The kind of cores you have matters as well as how many cores.

#

Same with Paper. Moreso with Folia.

#

If you only have like 2 cores you should just use Paper.

subtle fjord
#

yup yup.. what I expected.. so even with server cpu you will have to look at single-core performance..
I will test it out on an i9-13900 - only the performance cores. not ideal for sure, but for our number of players good enough.

timid grotto
#

regions will merge before they get close to bordering eachother to avoid issues with redstone and such

wild swallow
fair merlin
#

You can't.

subtle fjord
#

or if you use docker you can do cpuset.

primal oyster
#

You also do not want the regions to be that small either

#

You can end up having a bunch of other edge cases otherwise

subtle fjord
#

cooling is an issue, especially if you’d run on all cores. Also had bad experience with AMD chips crashing. Like Desktop CPUs are already bad as servers, but Intel are in my experience very stable still.

elder portal
# subtle fjord cooling is an issue, especially if you’d run on all cores. Also had bad experien...

Not sure if I understood what you said correctly. You're trying to say desktop CPU's are worse for minecraft servers than server CPU's? If so, then I'm afraid you're wrong. Especially Intel server CPU's have lower single-core performance than Intel desktop CPU's. That's literally why people use the desktop CPU's for minecraft servers. Can't say about AMD, since I've yet to build my new server rig, but it is going to be AMD.

subtle fjord
# elder portal Not sure if I understood what you said correctly. You're trying to say desktop C...

Nah, not what I meant, not sure how you read it that way, because even within that sentence I am pretty clear.
I am saying: there is a reason why server CPUs have lower performance per core - and always will have - compared to desktop cpus. Thats because they can guarantee cooling under 100% CPU across all cores without thermal throttling - as that is their main use-case.
But also because they are built for low chance of "crashing". And yet, we are in the unfortunate situation to have to rely on desktop CPU - as I do with my rack server as well.

YMMV, go with AMD if you have good experience. I got burnt and heard other DCs with Ryzen Desktop getting burnt when it comes to reliability / thermal - but I am sure there are also plenty of stories around Intel crashing - which comes to my main point: Server CPUs are just much more stable as hell πŸ˜›

elder portal
subtle fjord
#

hahaha.. yah.. like in general bad, but unfortunate necessity for MC..

urban delta
#

or just rent a server so you dont have to worry about cooling

subtle fjord
#

can't really, with my storage requirements I'd be paying a lot - but also where would the fun be?

urban delta
#

right

#

there's still a lot of benifits from renting a server than self-hosting

#

like you can choose the location

#

routing is probably better

subtle fjord
#

if you have the budget, for sure.. I use AWS for edge - which is quite premium network.

urban delta
#

I like OVH eco

subtle fjord
#

as edge? or for compute?

urban delta
#

For compute

#

yes but if you have experience for example

#

from what I see that guy does have experience

subtle fjord
#

always a thing of what ya need.. for smaller servers definitely makes sense to go rented.. at some point everyone outgrows a certain market/solution

urban delta

Hi, I have a small SMP server with 30 - 50 players, which core is better paper or folia. I was told that "folia gives better performance only on large servers where players (150+) are dispersed. Otherwise, it will perform worse than paper"

viral stone
#

Folia has overheads, the nature of that varies

#

if your players aren't spread out enough, you won't have any of folias advantages

jagged frost
inner swift
#

If all players are less than ~900 blocks from each other (realistically, a fair bit higher to avoid region merging which will then have higher thresholds for unmerging), then that'd mean everyone is on 1 region

#

If everyone is on 1 region, Folia will perform worse than Paper (sure, there's nether and end regions too but that usually has too little load to be advantageous)

naive fable
#

I would make a script to check how many regions you would get with folia, and then see if it would be beneficial

wild swallow
#

are there any known land claim plugins that are working with folia?

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'!

Thanks! It sounds like you use this on your Folia Server?

Opinions on this?

junior osprey

Do you think the ZGC is likely be better than these?

steep elbow
fair merlin
urban delta
livid crag
#

pause time isnt everything either. Just becasue it reports a smaller amount doenst mean it is better Despairge

paper siren
#

Note that you should use generational ZGC from Java 21 if you want to use ZGC

livid crag
#

I trust you when you mean to change the flags means you fully understand how the stuff works... We do not need those everything flags from back to yatopia days to come back Despairge

steep elbow
livid crag
fair merlin
#

The README is accurate for the moment. It isn't likely to get updated unless any of those things change. But there's still commits happening, just not to the README because there aren't any relevant changes to the README.

calm fable
#

so when i look at the gradle stuff it looks like, we go from mojang's obfuscated release and then applying bukkit/spigot/paper/folia patches is that correct?

bold osprey
#

there's a big risk that ZGC will just destroy your cpu cache, resulting in less performance, and will give more load on the cpu, often resulting in less performance for individual threads

All those benchmarks can't be similar to real usage, and in comparisons between real servers with real usage using different well configured gc, the difference wasn't noticeable, but you always have the risk of messing something up with not properly configured gc which will end up crazy

#

G1GC is really well tested, so if you just copy and paste aikar flags you most probably will be safe and the maximum performance gain of using other flags is like 0.1%-0.5% (if you're lucky)

finite hinge
#

ZGC and Shenandoah give lower pause times but also lower throughput

#

They take more CPU time from the actual code you're running for barriers to allow the GC to run fully parallel

#

That might actually make sense for Folia since the whole point is having a lot of slower region threads

#

For Paper? I'd stick with G1GC I think

#

Also that github linked above is for the client

#

For the client you probably also care about having lower and predictable pause times more than you care about losing a couple percent of performance, gives smoother frame times

paper siren
#

yeah slightly lower throughput isn't a problem with Folia, while G1 pauses might cause global lag spikes

finite hinge
#

To be fair unless your max heap is over like 100GB G1GC is usually champ

#

As of like Java 14 anyway and improving more every version

paper siren
#

the only downside of ZGC in below 32GB heap settings is that you always have uncompressed oops

bold osprey
primal oyster
#

how much memory were you allocating?

twin spindle
#

I can get jvm flags for Folia?

paper siren

just use aikar's flags, unless you run into problems with it, in which case you can provide spark profiles etc

Hi friends, I met a problem.
I have two players (including me) in my server, I am here at (256,64,-256) and my friend is at (768,64,-256)
Here, I adjusted the server's simulation distance to 8 and the maximum visible distance to 10, but using the /tps command on the folia server side, we get the result that we are still in one area (the first picture shows a total of two areas, one of which is the main world and one of which is the empty island world)
I was very surprised so I downloaded the spark plugin to analyze it.
But in this plugin, I found that both of us players were again in area #21 and #22.(second and third picture)

Here is the spark analytics link for my server.
https://spark.lucko.me/2HB2bUWfP9

Problem.
1.Are my friend and I divided in one region or two regions?
2. will this utilize the power of folia's multi-threaded computing?

Thank you so much!

spark

spark is a performance profiler for Minecraft clients, servers, and proxies.

viral stone
#

Yes

#

folia needs to seperate the world up into managable blocks of chunks, called regions; if chunks are too closed together, there is a chance they could merge

#

and, so, folia will treat them as one to avoid that issue

#

if you want more regions, people need to spread out as appropriate, current default config is like 900 blocks of seperation

#

if you have 2 players online, and there is an region with 2 players, it would generally be safe to assume that you're both in a singular region

silent current
#

Thank you so much!

(do note that spark is looking at chunk regions, folias "regions" are the "ticking regions" that it itself defines)

On a serious note here are the 4 libraries I have seen going around that may help you. There is not one I recommend more than another. If you plan on creating a folia supported plugin one of the first things you must do is have all processes that will use runnables and schedulers be replaced with Folia compatible ones. That is where these libraries will help. The second this is to have " folia-supported: true " in the plugin.yml.

When porting mcMMO I decided to use FoliaLib with HSGamer, TechnicallyCoded and Rockyers. Some of the changes to that library, came in part due to trying to make it easier to port mcMMO. I didn't think you'd know that, but yea some of the changes came from HSGamer.

# pseudo ibex Can you elaborate more?

It will be a github page like paper hangar and I will give you guys the admin panel for you to mark a repo of yours as working or not, then if it is working it will compile the plugin from the repo on every new commit and put on the website I made for this for people to download the compiled versions

If I knew you better I think I would be more inclined to accept this offer, but it could present a security risk for all who download the forks off your site.

E-2288G vs 2388G what best for paper,folia

viral coral
#

the newer the better

#

you could probably run a low playercount folia server on a 2388g

manic basin

2388g Better?

arctic tapir
#

the newer the better

manic basin
#

Ok

primal oyster

i do not recommend it

fair merlin
#

2288G is a decent CPU. But as with anything, it depends on what you're doing with it. There is no catch all "what's the best XYZ". It all depends on setup, administration, server use, etc etc etc etc

viral coral
#

calling a 7950x cheaper than a 2388g is a stretch

viral coral
#

no idea where you're buying servers then

#

a 2388g is not more expensive than a 7950x in 99% of the cases

fair merlin
#

A base 2388G from OVH isn't even $180/mo

#

Let alone $180 more than anything.

finite hinge
#

The 2388g system probably has more "enterprise" SSDs and such in it

fair merlin
#

That's buying the actual CPU.

viral coral
#

the vast majority are not selfhosting

fair merlin
#

That is not the same as renting a server.

finite hinge
#

Oh that's literally just the CPU

viral coral
#

and buying a 2388g from a consumer shop is shooting yourself in the foot

fair merlin
#

Yes a server Xeon is going to be more expensive at retail than a desktop CPU.

finite hinge
#

ARK says 2388g should be $600, AMD says 7950X should be $700

#

7950X is not that much in actual stores but I imagine the 2388g isn't either

134 region files doesn't mean you can use 134 cores, can you even have 134 regions in Folia?

I mean, I guess if you were doing skyblock that might actually happen but otherwise I don't think that's possible unless you're a several hundred player anarchy server or something

Hello I'm wondering : excluding missing API and the limited amount of plugins currently working on Folia is the actual server stable & crash free without major breakage in game mechanics?

Yes, seems to be fine gameplay wise and regarding crashes

livid crag
karmic urchin
#

They are using the 1.19.4 version if I'm not mistaken? I imagine a lot of improvements have been done since. Is the 1.20.4 version not being the main branch related to a lack of stability or it's just because it's the current version?

Dude, can you read what I wrote properly? Is there a proper NPC plugin that supports viaversion? I don't have any problems with folia. How logical is it for me to go to the support channel about viaversion?

daring nimbus
#

If you need something that supports ViaVersion, you need to ask ViaVersion.

#

Again. This is for Folia support. You are asking a question about a plugin running on Folia

left gust
#

Whatever you want, I wrote it there, it really doesn't help, it's just your show of superiority, it's extremely disgusting.

daring nimbus

Though it is very likely that there just is no NPC plugin that supports Folia and ViaVersion.

Or writing your own NPC plugin that supports Folia/paying someone to do that

Just because I asked a simple question on the folia help channel, I was bullied and warned that this was not the place. It's funny, I only got the opinions of experienced people who use it. Also, do you tell everyone who wants folia support not to use it? I don't understand.

sudden tusk
#

This is a reading comprehension issue. You are being told this is the support place for help with Folia itself, not about plugins running on it. As nobody appears aware of an option for Folia, it was recommended to not use Folia if you want NPCs and viaversion. That's pretty reasonable. Chill out πŸ™‚

is it possible? probably

are you going to get support in doing so? no

Is it going to be faster than paper? Probably not

arctic mulch
#

isn't folia only worth it to go for if you have the playercount for it since i would think having like 100-200+ players daily is fine with paper or pufferfish but if you get like 500+ then go for folia πŸ€”

finite hinge
#

It could be worth it with 2 players

#

You and a friend, basically running single player worlds with your own bases, farms, etc, but you can walk/teleport to each other

#

You probably aren't going to need more than what a single core of block/entity ticking can provide with 2 players but then again a single player can overload it so... depends on how crazy your farms get

It seems like there might be a memory leak issue with the latest version of Folia. I've been using it since 1.19.4, and when I updated to 1.20.4, the server often automatically shuts down with a "Java heap space" error.

Memleak

fair merlin
#

Or if the server only has 32GB

narrow bough
#

The server is running on a whopping 128GB of RAM, with more than 90GB of free memory available.

inner swift
#

In this specific instance, it's not really a container misconfig or similar

#

You'll either need more than 32GB of heap to run your server, or analyze a heap dump to verify if something superfluous is taking memory, that you can get rid of

#

There's a JVM flag to create a heap dump on OOM

narrow bough
#

The "/forceload list" command isn't working. Since I updated to Folia 1.20.4, the server crashes every 1-3 days, consistently with a "Java heap space" error. Regarding the "/paper heap" you mentioned, I'll give it a try after the server has been running for a day and see how it goes.

narrow bough
inner swift
#

XX:+HeapDumpOnOutOfMemoryError

#

If nothing is abnormal in the heap dump, then maybe your server just needs a lot of RAM, could happen especially in a niche case like Folia depending on what you're doing

#

Can't really tell an amount that works for your server's use case

narrow bough
inner swift
#

Looks right

#

Then if it crashes you'll get the heap dump

narrow bough
#

Thank you. I'm restarting the server now with this flag. Anyway, thanks a lot for your help!

#

Sorry, what I mean is not standard

#

What I mean is, on average, the server automatically shuts down within 2 days due to throwing a "Java heap space" error. It just happened again a moment ago.

viral stone
#

as said, you'd need to take heapdumps and see what's eating up the memory

narrow bough
#

now

#

I've added the "XX:+HeapDumpOnOutOfMemoryError" flag as mentioned by Kyle. I'll wait for the next crash due to the "Java heap space" error before reaching out again. Thanks to all of you!

ornate warren
# narrow bough The server is running on a whopping 128GB of RAM, with more than 90GB of free me...

Just to advise, we made the same mistake of allocating a whopping amount of RAM for XMS and XMX and kept getting lagged out - it turns out that what was happening is that the Garbage was building up to such a large amount that when the cleanup happens (which essentially does a 'world stop' while it completes) it freezes the server for so long that everything crashes out.

We since set XMS and XMX to be 15G and it has seen a huge improvement in performance as it cleans up more frequently but a much smaller amount of garbage and so the 'world stop' GC moment is much much smaller process and isn't noticed by players

thin anvil
#

how can I disable any mob or non-dangerous mob spawning

ornate warren
viral coral
#

that is a post from 2020

#

practically any garbage collector has seen improvements over the last few years

#

e.g. generational ZGC

viral stone
#

ZGC has advanced since then, especially generational ^

#

That post was also made on paper, where the majority of allocation is limited to like 2/3 threads, primarily the main thread

viral coral
#

from personal experience i've had generational ZGC be the only garbage collector that kept up with my allocation rate for minecraft with good cpu usage

#

but that is on a niche scenario

viral stone
#

ZGC already looks more attractive since the work over the past few years, especially with the generational improvements, and with something like folia, a lot of the dynamics change

#

but, at the end of the day, there is no magical bullet that works for all usecases, that's why you have gc logs and profilers, etc

ornate warren
#

Don't get me wrong, I'd love to be able to use every part of the top-end hardware we're running on, but this GC issue utterly hamstrung us for ages without us realising that the 'world stop' process for it was the issue

paper siren
#

that's basically useless info without knowing the version you ran

viral stone
#

ZGC basically minimises STW over G1 GC

#

but, it just generally has some more interesting "oh shit" behavior, like allocation stalls pausing threads

paper siren
#

but allocation stalls where basically solved in 17 already afaik

viral stone
#

Yea, I mean, I've not really tracked it much, tbqh

#

I'm still tryna catch up with everything ;-;

ornate warren
#

Ok that's interesting to note as we're on 17. We might give it a shot then. So we can basically set XMX and XMS to a larger amount using ZGC and we won't suffer the same fate we did with G1GC?

paper siren
#

depends on the actual issue

viral coral
#

yeah there isn't exactly any information to go off of

#

would also suggest just updating to 21

visual falcon
#

Would be nice to have a updated flags guide so people stop asking what is best to use.

viral stone
#

I mean, the guide is updated

#

very little has changed in the terms of G1GC that it implicates the advice there in any large manner

#

the only big thing is that maybe you can drop some of the flags in terms of letting the adoptive algorithms take over as they're a bit smarter

#

but, the guide is for paper, not folia, folia is an entirely different ballgame and so toying with different GC alsos kinda makes more sense; generational ZGC looks more attractive too in many respects but, it's hard to blindly recommend any of the modern GCs to people who don't understand this stuff

visual falcon
#

If possible to move on from G1GC and there is proof of a better type of GC and allowing paper to take more advantage of newer GC type would be nice, Not sure if thats possible though,

fair merlin
#

And if you're running Folia you should be thinking about things like what flags work for you, not blindly following defaults.

livid crag
#

Most people asking for β€œflag guide” will do just fine using aikars.

If you really want to fine tune it, acquire the knowledge first instead of seeking out what people claims to be the most β€œoptimized”

viral stone
#

ZGC is more finacy and you generally need to be more aware of how to diagnose it

#

G1 is generally more predicable and forward in terms of when it craps the bed

visual falcon
#

isn't Aikars flags old by now even if the guide is updated.

viral stone
#

I mean

#

java is java

livid crag
viral stone
#

MC is MC

fair merlin
#

There's also a difference between guidance and law.

viral stone
#

the flags may be old but stuff has generally not changed in a manner that causes any real big issues outside of MC wasting more memory so the 12G+ flags are probably more harmful than good

fair merlin
#

Most of our recommendations are just that - recommendations.

#

Often a good baseline.

viral coral
#

i could personally probably live without aikar flags in 2024

#

aslong as a modern java version is used

visual falcon
#

Wait so there isn't a way to improve say paper or folia to fully take advantage of a newer gc, even though mc uses G1 by default?

viral stone
#

We have a guide

#

that fits 99% of peoples usecases

#

noting that 99% of people do not understand how java works

#

do not understand or care to get invested into how garbage collection works

#

and do not have the skill or care ro access to figure out how to diagnise GC issues

#

aikars flags while old, are generally still fine and as close to a 'works for the majority' as we're going to get

#

Yes, some newer garbage collectors exist, generational ZGC looks really interesting and if I wasn't half dead and had a server still, might be fun to toy with and see how it performs, but, the nature of ZGC also means that it can act a bit funky in some cases

#

some cases which people running servers fall into, and while G1 GC will often not perform amazingly in such cases, we can generally see and understand why it's crapping the bed vs many of the newer collectors which will generally hide that by killing throughput

#

I'm kind of surprised generational ZGC ended up being a thing and being so good because I remember at the start of Shenandoah and ZGC they were arguing the generational hypothesis was a failure for modern programs

#

Although I suppose they were talking about HTTP servers...

viral stone
#

Yea, I mean, I get it

finite hinge
#

The application pattern for which the generational hypothesis is most true is stateless servers.

#

If you're storing any kind of long term state (for example, caches) you break the generational hypothesis and a generational GC does extra useless work and hits modes where it doesn't perform well

viral stone
#

like, their entire thing was that they wanted to cater towards stateless stuff in which memory is allocated for something and then tossed out at the other end

#

and, I get it, that's probably like, a good chunk of web apps in their ideal state

#

but, caches are hard to avoid in many cases

finite hinge
paper siren
#

pretty sure generations were planned for ZGC from the beginning, but they wanted to focus on minimizing work during pauses first

finite hinge
#

iirc a big thing for G1GC was to make it better able to adapt to things that break the generational hypothesis too, via dynamically designed regions or whatever

#

I guess I might just be remembering shenandoah, zgc kind of appeared out of nowhere for me

#

I was watching talks about shenandoah and following development of it though

paper siren
#

afaik ZGC can dynamically size the generations pretty well

viral stone
#

G1 does the dynamical thing, though many years ago it sucked, hence aikars flags

finite hinge

Also I swear shenandoah is reminding of what Mike Pall wanted to do with luajit's GC

ik what is multi-threaded

#

but is it multi-core support

#

ed

viral stone
#

it uses multiple threads

daring seal
#

my question

viral stone
#

your OS schedules that work over multiple CPU cores

viral coral
#

you know it's multi threaded yet you're asking if it's multi core

daring seal
#

I heard folia is multi-threaded but still use one core

#

I heard

#

heard

viral stone
#

it splits the world up into regions

#

those regions are run in parallal if you have the correct hardware

viral coral
#

anything multi threaded is multi core

viral stone
#

so, your regions are still effectively bound by the nature of a single thread, but, the entire point is that you can split the world up to use multiple OS threads for ticking

daring seal
#

ok

#

so can it slightly help a server with 10 people?

viral coral
#

no

daring seal
#

that live far away

viral coral
#

if you're struggling with 10 players on paper you're going to have bigger issues on folia

daring seal
#

they live seperately

daring seal
#

im just wanna try out new things

viral coral
#

are you a developer

daring seal
#

no

viral coral
#

folia isn't really in a state where you'd want to use it not as a developer

#

every plugin is essentially broken unless it specifically builds support for folia

daring seal
#

ik

#

I test them all out

viral coral
#

not to mention we don't distribute builds

daring seal
#

yes I know

#

I compiled it

#

and tested it with my plugins

#

works fine

#

I just want to know if it does any changes

viral stone
#

Unless you're actually having performance issues which can be solved by more cores, it will over 0 benefits for a lot of caveats

daring seal
#

tbh most server hosting service online already inclued folia

#

like exaroton and shockbyte

viral stone
#

and most server hosting companies are purely there to bait people into handing them cash

#

it's hardly a metric for anything

daring seal
#

does it help with the fact people building like 1000000 exp farm in my server

viral stone
daring seal
#

true

viral stone
#

if your tick is within 50mspt, it will offer pretty much 0 benefits

daring seal
#

my tick is 55

viral coral
#

at 10 players you can definitely get that down

viral stone
#

okay, and now you're telling an inconsistent story

daring seal
#

?????????????????

viral stone
#

you said that you're not having performance issues

daring seal
viral stone
#

So, you are having performance issues

daring seal
#

kinda

viral stone
#

then, who knows, if you have enough CPU cores folia might be able to help

daring seal
#

16 cores

#

my old pc

#

16 cores

#

i forgor

#

maybe it isn't

#

but I remember it is

#

6 core maybe

#

my fault

#

6 cores/12 threads unlocked

balmy tusk
#

which mc versions does folia support?

#

is there a version for 1.16.5-1.17.1?

lofty magnet
#

no

balmy tusk
#

so whats the lowest

lofty magnet
#

1.19.4

balmy tusk
#

ty

lofty magnet
#

(of course you should always run latest)

balmy tusk
#

also i've seen some info on the main page of folia project about chat issues? does it still happen?

#

it mentioned that chat was enabled 4fun and it casued everyone to be kicked

daring nimbus
#

Might have been proxy related, iirc that test used a proxy and chat signing and proxies is still not a great combination

balmy tusk
#

as i already have like 3-4 separate lobby servers to fit all the players

#

so merging them into 1 server but spreading them across few lobbies at the same world just in different places

#

was hoping that'll make it

daring nimbus
#

If it's just separate lobbies I would stick with Paper

balmy tusk
#

yeah i was hoping to merge it to make it 1 big lobby

#

it'd be more efficient and cheaper way to do

#

cuz i have 2 dedicated machines just for lobby

#

so i could handle am all at one machine

daring nimbus
#

If they are separated anyways running four servers will be more efficient than Folia.
And you won't be able to have everyone in the same location with Folia either. It only works if people are spread out a lot

balmy tusk
#

but my goal was to have 1 server instead of 4

#

for that purpose

daring nimbus
#

I mean that would work in theory, but in my experience the main bottle neck with lobbies is when something goes down and you get 200 players joining the lobby at once. And Folia isn't really gonna make that better

#

idk how many players you have in lobbies though that you need that much

lofty magnet
#

just slow down the switch on the proxy by keeping clients in the configuration phase ;D

fair merlin
lofty magnet
#

?

#

that was meant as an actual solution to too many clients joining a server at once

#

keeping them in the configuration phase for a bit on the proxy should slow them down (traditionally one would use a void server for that)

fair merlin
#

By slowing down the network switch?

lofty magnet
#

by not having 200 players log into one Minecraft server at once

viral stone
#

I already have logic in paper which does kinda similar just to delay shoving them into the world

lofty magnet
#

but I assume that is limited to the client timeout duration or is that during the configuration phase now?

viral stone
#

I have no idea, it was designed for short term, so there was no real care to implement stuff like keepalives in there

ornate warren
#

Question, on this server we have an issue where sometimes we can have 50 players on without much in the way of game-impacting lag, but other times with half that many players on (like in this image) and there's clearly some players up to things that are causing lag.

Is it worth us spending time fine-tuning our settings as a Paper/Pufferfish installation, or as an SMP server would we be better off looking at Folia to solve this issues because we're clearly not utilising the hardware fully enough?

image.png
viral coral
#

screenshots of sparks are useless

ornate warren
pseudo ibex
#

Pufferfish?

livid crag
#

I think you are in the wrong discord pepela

viral coral
#

with the amount of plugins you'd have, probably a rough time moving to folia

#

and you should definitely be able to hold like 100 players with paper/pufferfish/whatever

ornate warren
#

Yeah we're thinking more in terms of reducing the number of plugins if we did

viral stone
#

CPUs with ecores are generally a bad idea

livid crag
#

more than half of your plugin dont current support it yeah Despairge

viral coral
#

good shout cat

#

yeah you should disable your e-cores

#

probably fixes your performance issues

finite hinge
#

You'd be reducing your plugins to about 3

#

Unless you write your own replacements

#

And your players would have to be building bases 1000+ blocks away from each other

ornate warren
viral coral
#

no idea

#

definitely not helpchat though, probably not going to find someone competent for server optimization there

livid crag
#

Unless you are using bat for modelengine or some custom entity replacing bats.

ornate warren
viral coral
#

disable your e-cores

#

even better would be switching to the 7950x3d and avoiding anything intel

completely new to folia, but how do i download folia?

#

ive researched this, and found that i had to compile it

#

but when i did, i kept getting errors

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.

fringe oriole
#

ah ok.

tacit tartan
#

If you're having compilation errors, send them here and we can point you in the right direction, but generally if you find debugging compilation errors difficult, that's a sign that folia in it's current state is probably not right for you

fair merlin
#

@left gust As the link above says, we specifically are asking people to not provide builds or link to builds. If you can't build Folia yourself you shouldn't be using it.

left gust
#

Fuck translate

#

Of course, I can compile it myself, it's a very simple process, but maybe my friend's computer might be bad and I thought he would test it, so I talked about the project. Also, why are you so strict about the spread of builds?

#

@fair merlin

fair merlin
#

As I said, if someone can't build it themselves then they shouldn't be using it. If they encounter issues building it then this channel is here for them to get help with that.

#

Building it is going to be the least of the issues they encounter.

left gust
#

I don't think the issue is unknown sources. The source I mentioned is a github project and it compiles using action. Are you worried that it will spread more and demand support?

cobalt sierra
#

Folia is absolutely amazing. You guys have done an amazing job on it so far! Can't wait to keep up with the new changes to it over this year!

finite hinge
#

Because if you're using Folia you almost certainly have to be writing your own plugins at this point

daring seal
#

According to paper mc document

narrow bough
#

It seems to be a "Java heap space" error caused by Spark?

paper siren

any recommended plugin to disable minimaps

#

Is this legit?

fair merlin
#

For mods that support it and behave nicely and for non-Folia servers, sure.

daring seal
#

ok

#

is there any anti griefing plugin for folia

fair merlin
#

But a modified client or a modified mod that won’t obey that flag will still have a minimap

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.

Will Xeon E5 2683v4 (16 cores/32 threads, 2.6 GHz) be better than Xeon E5 2678v3 (14 cores/28 threads, 2.8 GHz) for Folia if there are 8-10 people playing on the server? How much RAM do I need?

fair merlin
#

But the base frequency on the 2683v4 is 2.1GHz, with a boost of 3.0GHz. Not 2.6

#

The 2678v3 is 2.5GHz base and 3.1GHz boost.

near hedge
#

as i heard only for 1-2 cores

#

why not?

fair merlin
#

I wouldn't say wasting everyone's time, but yes, most likely for only 10 players Paper is going to be better suited for your uses.

#

This depends on the server, the players, what they're doing, etc etc.

#

I don't think a blanket statement like this is helpful.

near hedge
#

Our players like farms and high performance stuff.

fair merlin
#

Or you aren't going to get the benefit of Folia.

#

So large maps, some plugins aren't ported at all, some just won't work, and some features are disabled.

#

So it's worth exploring whether it's truly a good use for you.

#

If you just want to try it, go for it. But be aware that it may be a bit of fiddling to get things setup.

#

And/or you might have to sacrifice some features.

idle furnace
#

And might be worse every time a new version gets out, for normal Paper sometimes plugin owners take ages to update, imagine in here

fair merlin
#

Yeah Folia is very likely on a slower update cycle.

near hedge
#

Also wanted to ask: does Folia change the behavior of a vanilla minecraft server like PaperMC? Redstone, block upgrades, etc.

idle furnace
#

One question, is there a Folia channel more dedicated to betatesting plugins?

fair merlin
#

So that would be more like whatever Discord those plugins have.

idle furnace
#

I have something to try out, that requisers some users at same time

fair merlin
#

Same with Paper.

primal oyster
idle furnace
#

I mean the plugins we are porting to Paper

primal oyster
#

but in some small features it slightly changes (none of them are really vanilla vanilla mechanics) just visuakl things maybe

fair merlin
idle furnace
#

I kinda finished preparing a minigame plugin for folia, ans this server seems to me be thest place to try out

#

but there is no chan to anounce or request for help testing stuff

fair merlin
idle furnace
#

so how to potentiate the pluging support to folia?

fair merlin
idle furnace
#

you already know it is harden then for other server to make decent support for it

fair merlin
#

Or throw it up on your server.

idle furnace
#

friends do help, but the experts are all here

viral stone
#

We don't want to be the server that people flock to for "please help me test my plugins"

idle furnace
#

and possibly someone willing to help, that my idea

fair merlin
idle furnace
#

why not have a chan just for it? A chan can be mutted if we don't want to see the activity

viral stone
#

Because then we have to moderate it

fair merlin
#

Yeah we just avoid advertising in general.

idle furnace
#

ok, I understand

#

makes sence, quite often people abuse

viral stone
#

We've generally been okay for reputable people to try to organise stuff, but it becomes a huge headache when you start having 20 people a day show up pestering for people to join their servers to just "please help test"

#

it just creates a lot of drama because all of a sudden we're supposed to care about the randomer who joins and griefs the place, as well as the headaches around people who basically try to use it as a means to advertise, etc, etc

idle furnace
#

understandable, yep

#

so if i anount a server for testing this, would be considerd spam?

#

we are kinda between the wall and the sword, if i explain my self right

#

testing is a part of the development cycle πŸ™‚

#

but i understand

#

true true

viral stone
#

part of the reason we don't want people "advertising" for testers is because most people can't be arsed to join randomers servers to test

#

and so it literally just ends up in hours of spam as they try to coax people into joining their server

#

which then ends up with somebody seeing it, joining the server and griefing or something stupid, and then all of a sudden we're expected to moderate them for something they did on a block game server that has nothing to do with us, etc

idle furnace
#

yep, yep but becomes hard to test this under heavy conditions. Not owning server makes it hard to test it decently. Will continue to "play with my self" πŸ˜„

#

I don't plan to make marketing, just have proper testing on this challenge but yes, having a hard time with the testing part

#

I am pretty sure it will not work as nice with 20 players on it

#

the Schedulers might get mad with me πŸ˜„

fair merlin
#

Sorry @idle furnace that's part of the advertising we don't allow.

idle furnace
#

it is ok

Does chunkloading require high-level computation?

#

I would like to know why chunkloading does not use the gpu

#

Oh, of course, I'm speaking from the server's perspective

paper siren
#

you likely mean chunk generation, and the reason it's not using the GPU is because most servers don't have GPUs and writing code designed for GPUs typically differs from what you'd write for CPUs

When I deleted Spark now the server has been running stably for two days, which would have been impossible before I deleted Spark, maybe the version of Spark I'm using is too outdated? I was using spark-1.10.52-bukkit-folia-patch-3.jar. The above is limited to 1.20.4 only, as I was using 1.20.1 along with Spark and they both worked fine.

spark's background profiler realistically shouldn't cause any issues aslong as you're on a platform supported by async-profiler

#

so anything that isn't windows

#

it profiles it for a long duration but at a very high interval

livid crag
#

How you know it’s a leak SUS

paper siren
#

The background profiler should only keep 1 hour in memory afaik, so that would be a bug then

bold osprey
livid crag
#

let's uhhh get verifiable evidence first before treating it like the truth...

bold osprey
#

well, patch 2 of spark had a problem that it couldn't stop any kind of profilers to give a link, and they started spamming a lot in the console if we tried that, so it's not that far from the previous problem

Ep37. How To Compile Folia - Minecraft Plugin Development

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...
