Server Snapshot Performance Backports

_NOTE: This mod is currently archived as there haven't been any performance optimizations to backport in the recent time_ Backports server performance improvements for the latest release from the latest snapshots. Details about the optimizations can be found in the [changelog](https://github.com/litetex-oss/mcm-server-snapshot-performance-backports/blob/dev/CHANGELOG.md). ## Motivation/Why does this mod exist? Snapshots (e.g. [24w33a](https://minecraft.wiki/w/Java_Edition_24w33a)) can contain extreme performance improvements for servers. However it may take months until we see these improvements finally shipped in a release. This mod contains selected extracted improvements from the snapshots and backports them into the latest available release. 1.21.1 Idle CPU usage comparison Before / Without mod:  After / With mod:
