Describe the bug
Serverside performance with C2ME and Valkyrien Skies 2 installed is heavily degraded. Disabling C2ME solves the issue.
I haven't yet made a test-case server with only C2ME and VS2 installed, however the Spark profiler I ran seems to show that mixins (?) in chunk logic by C2ME cause some sort of bottleneck or persistent chunk unloading even when a vehicle is not actively being dismounted from in VS2.

Will attempt to make a test-case server with only C2ME and VS2 installed and latest devbuild soon, and this may boil down to being a issue that needs to be fixed by VS2 authors.

To Reproduce
Steps to reproduce the behavior:

1. Have Valkyrien Skies 2 and C2ME installed.
2. Dismount from any VS2 vehicle (?)
3. Server performance is heavily degraded until restart

Expected behavior
Performance to not be degraded with these mods installed.

Checklist

• I am using the official version of the mod.
• I tried the latest development version but the issue persists.
• I searched for similar open issues and could not find an existing bug report on this.

Try reproduce with a normal HotSpot JVM.

HotSpot JVM

This was reproducible with the stock Debian repo Java (OpenJDK 17), and the performance was even worse without GraalVM EE's optimizations. Here's the profile I got before swapping to GraalVM:
https://spark.lucko.me/Ciis3L2VFf?hl=1180,1531,1536

openjdk version "17.0.10" 2024-01-16
OpenJDK Runtime Environment (build 17.0.10+7-Debian-1deb12u1)
OpenJDK 64-Bit Server VM (build 17.0.10+7-Debian-1deb12u1, mixed mode, sharing)

As stated, I'll try and reproduce this on a server with just C2ME and VS2 pretty soon
