Hello! I've got a modded save running that I'm having some pretty major performance issues with. My UPS is around ~45-50, and there appears to be a pretty decent sized memory leak (2mb/s)

My system hardware is (should be) far, far plenty. I have a 5800x3D w/ 96GB of RAM (I know it's weird but I pinkie swear it's not the problem) and a 3080Ti. We just touched down on the three beginner planets on our save, and we don't have any delusions of megabasing or other such grandeur. Our base isn't pretty, but it also shouldn't be UPS hogging.

I'm more than willing to drop a save, screenshots, logs, whatever you need - losing my mind trying to fix this :<

okay, i ran the kill all enemies command as a desperate last resort and that seems to have brought my ups back up and temporarily stopped the memory leak?

Press F4 and enable show-time-usage, then post a screenshot to diagnose the issue

enemies who want to attack you but can't find a path will constantly look for a path to your base. if you're on an island or you've made a moat or something and there's lots of biters in your pollution cloud who can't get to you, it causes lag

looks like it's all coming from "entity update". can you screenshot show-entity-time-usage?
