Dedicated Server lag With 167ms for one Update

[StackOverflow]

The dedicated Don't Starve Together server I set up occasionally experiences severe lag, which resolves itself after a few minutes.

I attempted to capture the profile.json and found that each Update takes over 150ms to complete.
However, I can't pinpoint the exact cause of this issue—perhaps it's due to a certain mod? How can I identify the root cause from this data?

profile.json

Edited July 7, 2025 by StackOverflow

Probably a mod that does something with Entities, as this line mentioning the EntityManager.cpp appears 15362 times in the log:

{"cat":"dont_starve","name":"GetEntityByGUID","pid":0,"tid":4136092288,"ts":674464,"ph":"B" , "args":{"src_file":"../source/simlib/EntityManager.cpp","src_line":193}},

Not sure what it (the mod?) does, but it seems it tries to access all entities at once or something? No idea.

Then what can I do to find the caller of GetEntityByGUID

I've checked the profile.json when game runs smoothly, GetEntityByGUID is also called more than 15000+ times. So I don't think the issue is related to it
