Entities are taking up 40% of your ticks, some sort of command handler taking up 10%
how am I supposed to do to fix it?
I believe 8 Dedicated Threads of a 5800X should be able to handle atleast 30-40 players smoothly.
things get harder when you also add 539 villagers into the mix though as one example of your lag issues
We can't really afford to reduce the amount of villagers as it's an SMP Server
So, we should upgrade to better hardware?
Change the villager logic if that's acceptable, cull them if that's acceptable, attempt to address the other sources of lag, or update to better single threaded performance
8 threads means nothing when most of the logic is single threaded
How do I do that?
