The **Concurrent Chunk Management Engine (C2ME)** is a Fabric and NeoForge optimization mod focused on accelerating chunk generation, loading, and saving in Minecraft by using multiple CPU cores in parallel. It targets heavy worlds and large bases, reducing lag spikes and improving frame time stability on any Minecraft server, especially during intense exploration or fast travel.
C2ME keeps vanilla world generation logic intact while reorganizing work across threads for better scalability and performance. It supports many modern Minecraft versions and works alongside other optimization mods. At BoxToPlay, we recommend it to enhance the responsiveness and smoothness of your **Minecraft server** without altering gameplay balance.
