C^2M-Engine, or C2ME for short, is a Fabric mod designed to improve the performance of chunk generation, I/O, and loading. This is done by taking advantage of multiple CPU cores in parallel. For the best performance it is recommended to use C2ME with Lithium and Starlight.

Concurrent chunk management engine, it's about making the game better threaded and more scalable in regard to world gen and chunk io performance.

C2ME is not production ready and still pretty experimental. So backup your worlds and practice good game modding skills.
