Description
What is this?
It's in the name! It uses mods to optimize your Minecraft server's performance and reliability. It also includes mods that prevent x-ray and are server-breaking.
How do I install?
Load the modpack into a supported launcher. Copy the mods from the mod pack instance's folder and paste it into your server's mod folder. This is currently a Fabric-focused modpack. There is a NeoForge version in this project, but mod support is limited so it is more cutdown.
The Mods
- FerriteCore (Decreases memory usage)
- Lithium
- Krypton (Improves the Minecraft networking stack)
- Concurrent Chunk Management Engine [C2ME] (Improves chunk performance)
- NoisiumForked (Optimises worldgen performance)

- Alternate Current (Reduces the lag caused by redstone dust)
- CrashExploitFixer (A port of Papers Improve-tag-parser-handling patch, to fix a server crash exploit)

- Async (Improves the performance of entities by processing them in parallel threads)
