Help with server lag, TPS dropping frequently due to unbeknownst reasons
I have been having trouble with my server while trying to find out the cause of lag. My fellow team and I have been having issues trying to pinpoint it, and we are incredibly stumped. It is greatly affecting the server to the point that people are dying because of it. We usually used the mod Observable to find out said reason but that mod has been untouched. Here is the Spark Profiler for anyone wondering what it looks like: https://spark.lucko.me/ng7M7RlKHN If anyone can help figure this out, we are very much in needed for help

I see a lot of power going to LootContextPredicate.test(). not sure what this is or if it's normal to be taking up that much of the tick. I can also see that there are a ton of entities, and that seems to correlate with the increase in lag

I also used this program
with this and im still not sure
thats what i think, but idk how to find out particularly what it is
Its just almost becoming unplayable and I'm going honestly crazy trying to solve it
@Specs has this always happened on the server?
And does it still occur if all players are off the server?
Here and there, but not last "season"
The thing is the mod that seems like its causing lag doesnt seem to be the problem
Looks to be an issue with custom NBT data being written to player entities
Likely a plug-in or mod causing the issue
Don’t think you have much of a choice but to find out which one that is
I’ve never seen player entities take up so much CPU. Think something you have downloaded is broken
I think its maybe vanilla refresh
I just dont know what that something is
!binary
Binary search your plugins
Remove half of your non-essential (ie not things like PAPI or LuckPerm) plugins and see if the problem is fixed.
If it still persists, the cause is in the half still installed.
Continue to halve the remaining plugins until you've narrowed it down to a single plugin.
Congratulations, you found the culprit.
