Hello,

Recently updated my ProtocolLib and have been experiencing extreme lag that pops up spontaneously and will often crash the server. I am running Spigot 1.11.2, and the latest dev build (v4.4.0). I have the dump thread posted in a pastebin below. I've been updating other plugins and making sure it's not any other plugin, but so far, it only brings me back to ProtocolLib. If I'm missing anything or didn't see something else, please let me know. Hopefully you're able to find the issue!

Yeah I noticed a similar performance issue while doing some profiling of my own. Currently experimenting with a different map implementation.
