Why is my server performing so poorly when 3+ people are on?

my pc specs are 32gb ddr4 ram, 5800x, m.2ssd

Datapacks/mods that use datapacks are your issue

can you expound

etc

the list is really REALLLLLY long

datapacks are slow as FUCK

ideally, use none of them

like

none

mods are like 100x faster than datapacks

so your lag is from those

the first screnshot

"command function manager"

is referring to mcfunctions running

which are the scripts inside of datapacks

they're not compiled like java code

they're interpreted

which makes them excruciatingly shit for performance

and they're taking up 40% of your CPU time

No other solution?

no. datapacks are bad. one or more are trashing your performance. find the one or several that are doing so and remove them. that's literally all there is to it.

I'm using datapacks because I would rather people be able to play without going through the process of installing mods but I see

yeah well, you've overdone it

also

there are server side mods

that don't require client side installation

anything a datapack can do serverside, a mod can too

check the info in the sidebar on modrinth

on the mod

and see if it says client or server

if it says server

then it doesn't have to be installed on the player's game

but this IS without a shred of doubt

the one problem

you have overdone datapacks

your one solution is un-overdo the datapacks

I did have a bunch of mods installed that say client/server side but they didn't work :v

if they say ONLY server side

is what I meant

if they say both, the likely require both

Ahhhhhh

That makes sense then

but that's not a universal truth

some say both and can be EITHER

but in any case

No sure way to tell? But generally mods that say server side means players don't need to install them?

there are a few ways

here

I'll run through em

this is from sodium

it only has effect client side

(performance)

yep understood
