The second-best server option always uses the maximum CPU and memory, and I don't know how to fix this.

#

This is with one person on and very few mods

Can you use spark to get a report? I might be able to pin down the problem.

ripe halo What is spark

Spark is a plugin you install on the server. It gives details reports about the server.

I have it installer now what with it?

#

spark profiler start and spark profiler open

#

server-side distant horizons is extremely CPU-intensive

#

importantly, does the server actually feel laggy?

#

Yes pretty badly sometimes

#

and can i do client side only distant horzions on the server?

#

[04:25:15] [Server thread/WARN]: Can't keep up! Is the server overloaded? Running 2000ms or 40 ticks behind This is a line of code im getting

#

Now it stays active just laggy

#

i would try disabling distant horizons on the server see if just that fixes the lag issues

#

you might be able to tweak its settings as well

#

I did that it was better much better but only for a couple people at a time when I have my 5 players on at one time the server is still very laggy

#

This is how it goes randomly up to 100 CPU and always a 100 memory and it can be really bad at 100 cpu

You could try this mod: https://modrinth.com/mod/tt20

This does not improve performance
This only changes how certain gameplay behaves when TPS is low so it doesn't actually feel laggy, despite the server lagging

TT20 (TPS Fixer) - Minecraft Mod

TT20 helps reduce lag by optimizing how ticks work when the server's TPS is low.
