Modpack: Better MC v9
Minecraft Server: 1.19.2
Fabric: 0.14.9
Eden Ring: 0.6.4
Server Size: ~7 players

I ran a profiler for 30 minutes using spark and it showed that edenring was using 15% of the server thread. Noone on the server had even been to eden ring yet, and noone was on it currently. I would expect eden ring to use 0% of the server thread when no players are in that dimension.

Yes, it's from BYG. As it checks hash map each time any blockstate is checked it causes performance issues

10% from these 15 are not from Eden, they are from another mod that changes blockstate handler

This is a normal usage of resources:

If it is larger than you have other mods that alters blocks logic, or you just have too much entities

Ahh good catch, sorry I missed that, that makes sense. Thanks for the quick reply!
