Can anyone help me with server performance?
I'm going to start a modpack server with my friends with a machine that we bought to be our private server, I'm the one running it and I'd love to have some help on how to improve the server performance so it doesn't crash.
I'm using Debian, CasaOS into Crafty to use it as my server manager.
Machine specs:
CPU - AMD Ryzen Pro 4650G
RAM - DDR4 16GB
SSD - 512GB
Right now I'm prerendering the server, since that was one of our main issues in the past, but it seems like the speed ain't the best, I'm rendering at an average 20 chunks per second rn
The CPU is being used at it max speed of 3.70GHz, sometimes going to 4.20GHz, but I just really want to understand if it will sustain a maximum of 8 players playing at the same time.
Thanks for the help!

is this home hosted?
yes
oh, and I forgot, the modpack is ATM 10
Rough, ok
get a spark report first
!spark
ahem
!spark
:ugh:
wtf
akhksajk they don't want to help us huh
Spark Profiler
Spark can be used to see why your server or client is lagging.
Users can share a spark report via
/spark profiler start --timeout 300 which creates a report after 5 minutes. The spark report is useful in debugging why your server is lagging, so ideally you should always provide one while asking for support.

i'm not using the server yet, we will be using it in like two weeks or so (I'll be gone therefore I'm using this time to prerender the chunks)
there it is
I see, ok use
servercore mod for performance helping (make sure to config the mod)
Lower view distance to 6~ by default
Pregen at least 10k radius
thats about all I can say
oh and flags
i'm now rendering some nether chunks, in a radius of 10k i think?
Not bad
when I have the spark report I'll send it here
make to pregen the custom dimensions too
but like 5k there
I've already rendered the overworld in a 15k radius
thats a lot
therefore the 20cps that I mentioned in the report
about the flags.sh, which file should i change in the server config?
actually, is it a file or just the java arguments?
the variables.txt
if you dont use a panel
java args
atm10 comes with a utix_args.txt file that is used to start the server
whatever looks like it uses arguments put it there
will do!
okay 😌😌
and how do I setup the servercore properly?
Config file is really simple. tons of comments on what each thing does
okay, i'll check it out and if I have some more doubts I'll come back to it
:thumb:
I'm just really afraid
?
8 players at once is quite hard
but 5 and under possible
because we bought this machine and I did a lot of research of what it should have to play properly and I'm afraid it wont work that well hahaha
how much did you pay
that would be the maximum, I think that the average will be like 5/6? and still then i doubt it a little
230€
Yikes
you got scammed out on some parts ngl
i bought it from minisforum
oh
it's a refurbished machine
tho
Ahhh
okok i just checked the cpu
its not bad
oh man fr
you just made me sigh irl
32gb ram wouldve been perfect for you
a big oof
its Good, but its not Mc good
i'll try to up it to 24gb/32gb if i can
24 would be fine
😭😭
then you can allocate 16gb to mc
ngl you wouldve been better off paying for a host for like Annual price :YEP:
I have like 14gb allocated to mc rn
do 12
or 13
14 gives a very light amount of ram to the system
maybe also add Swap ram :hmm:
if its a m.2 ssd
it's just because we usually pay once per summer, and we end up paying something like 30€ for 2/3 months and we'd like to have something a little bit more permanent
I see
I asked some stuff about this computer before, and people said it was okay and could run a modpack so yeah :/
even with those requirements I asked before
I pay 50 euro a month for a dedicated server off Hetzner
128gb i9 9900k 2tb :extraworried:
The modpack can run, atm10 is on the heavier side
I've tried to run atm9 and its a bitch
:ugh:
oof
on a 5950x Mind you
now its a 7950x :YEP:
well like 3years ago i tried to run a modpack on a i7 4970k with ddr3 12gb
was an old pc
so i started looking into stuff like this
i had a 32gb 4790k :3
and i really wanted to be able to provide a good server to my friends now ahhaha
I get it, also are you behind Cgnat or have a static ip?
what should i upgrade to be able to make the server run better?
like ram I get, but idrk a AM4 socket cpu that would be good
the biggest concerns rn is
Storage space, and Ram
its a laptop cpu. not full size since minisfourm does that iirc
static i think? for now i've only used a static ip (+ i have no idea what cgnat means i'm sorry :') )
cgnat = you Fucked if you are behind it
!cgnat
fucking bot
ok anyways
Yeah
i think it's static, I'm also thinking of portforwarding it, since only friends will be playing on it
yeah
or playit.gg :pepe_shrug:
still about this, as far as I've noticed the server doesn't push the CPU that much, at least of what I've noticed
I was thinking about it too, but it's a plugin only? and I didn't really want to meddle with that rn
where do i find the spark file that the profiler generated?
itll give a link
if you cant find it
run
spark profiler openokay, i'll get back to you in a few minutes then, it seems like there wasn't one running before
ty
spark
spark is a performance profiler for Minecraft clients, servers, and proxies.
there you go!
Yep so far so good, the jvm flags would be a big help
Also a small pay to use mod is Performant by someaddons, its a insane game changer for some servers so you might wanna look into it. entry price is like $5 for the mod and support
oooh okay I'll check it
what are the jvm flags?
java arguments = jvm flags
same thing just 2 diff ways to say
oh okay, makes sense
i can send the args file that the modpack comes with
this is the args file that I've talked about before
the jvm flags that I have set up right now are the following
Hm
java -Xms1024M -Xmx14336M @libraries/net/neoforged/neoforge/21.1.133/unix_args.txt nogui
Whatever that is, add it there
this is the main server execution command that the server runs first
yep thats where youd add it
it's already added then!
gg
I've now cheked that flags.sh website that you've sent, and it shows a WAY different jvm ahahah
You have a panel?
Crafty
ok
uhh leave like 1gb overhead for crafty then
so xmx is 1gb less then what it is
i'll lower it to 12gb as you mentioned before
yepyep
about this, the performant is only for forge, not neoforge :/
They have neoforge 😉
it might not say it, but its 100% neo suppoirted
oh nice
I'll check it when I'm back then
+ thank you for the help fr, you've been really cool
and since i've joined this community no one was ever so helping as you've been today :)
:thumb:
Mods are my jam
you mind if i add you on discord? or it is a nono for you? :)
As long as you dont dm me often for support sure :eyessus:
i won't do it dw 😌😌
thanks 😄
i'm just kinda worried that this thread closes while I'm gone and i won't be able to have someone to help me ou with stuff like this hahaha
if i need some more troubleshooting help I'll open a new thread and hope that you'll see it :D
there have been threads open for Years
ur fine
oof thank god then 🙏
np
i've looked a little bit more into it and this one is a full size one! + it can be upgraded in the future to a 5800X3D (i've done some research and this is one of the best single core AM4 cpus)
niceeee
about this, could you help me a little with this when you have time? :))
what os are you using
debian with casaos
hm not too sure. try googling it could give a good answer haha….
hey!
just checking up, I've reduced the dedicated ram to 12gb, changed the jvm args to some different ones that were recommended in the atm discord server for a server with 4+ cores and 8/12 dedicated ram, these are named ZGC (i can send them to you if you want to check them)
and also installed servercore limiting the view distance to 6
about this, didn't find a good one just searching casaos swap ram, will check later with debian swap ram
