Hello, I would like to ask if there is a way for protocolLib to not consume so much, I attached spark.

As you can see in the hottest code path you provided the plugin with the package ce.ajneb97.managers at the bottom with 3.37% is probably most likely that reason for the slightly higher CPU usage. So try to identify the plugin and maybe ask the authors about the higher CPU usage.

I am seeing a lot on my server that can't seem to be traced to a specific plugin -- yes high usage from LibsDisguises and Mypet, but that's only around 3%, compared to 6% from ProtocolLib itself:

I don't see the issue here, in your screenshot all packet listeners of other plugins combined us up about 80-85% of the total runtime of ProtocolLib and the rest is overhead. Seems fine to me.
