Saturn Mod is a free and open-source performance mod for Minecraft Forge designed to optimize Minecraft’s memoy usage, It works on both the client and server, and doesn’t require the mod to be installed on both sides, However, the benefits of running Saturn are pretty small as of the moment. If you aren’t using it already as well, Canary Mod (Forge) and Smooth Boot Mod (Forge) both pair great with Saturn and are fully compatible.

Features:
- Fixed biome temperature cache memory leak which eats a lot of memory, now it gives a huge performance boost to the memory.
