Forge server - low resource use and lag

[Thundercatsffs]

Hi everyone!

Im running a single VM on my Proxmox type 2 hypervisor.
That VM has 4 cores (3770k cpu) and 16GB RAM as well as a single harddrive with about 200GB worth of space.

My issue:
Ive installed a Minecraft Forge server, that worked well apart from some bugs with my mods... go figure.
Now tho, the server keeps having some sort of a performance issue. It complains about the server being overloaded even thou its barely using any cpu power, uses about half of the 12GB dedicated memory and a single user running around (me).

Anyone with similar issues or with any piece of advice? This is the first time i run a Minecraft specific server so i dont know whats to be expected tbh.

Worth noting:
Forge version:
40.1.79 (due to mods used).
Minecraft version: 1.18.2 due to mods used.
About 30 mods running, some pretty heavy such as Create, Immersive engineering and terralith used for terrain generation.

You can use spark to profile the server whenever the load increases to see where the performance slowdowns come from.

Did you ever figure this out?

If you are having an issue, you should start a new thread and post logs, and explain your issue.

Asking people if they figured out something on threads that are 1+ years old won't get you help very fast.
