Server Snapshot Performance Backports

Backports server performance improvements for the latest release from the latest snapshots.

Details about the optimizations can be found in the changelog.

Motivation/Why does this mod exist?

Snapshots (e.g. 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.
