:zap: What is HariMT?

HariMT is a highly optimized fork of the Async mod (originally by Bliss-tbh). It enables multi-threaded entity ticking, allowing your server to process entities in parallel across multiple CPU cores.

Simple keep TPS 20 when your server have 2000+ mobs

I have rebuilt and patched it specifically to resolve critical crashes and compatibility issues found in the original version when running with modern optimization mods.
