## What it is
Lithium is a free and open-source Minecraft mod that optimizes many areas of the game engine to improve overall performance without changing gameplay mechanics or visuals. It works on both client and server, supports Fabric and NeoForge mod loaders, and is designed as a drop-in mod compatible with most other mods.

## Use cases
- make my minecraft server run faster
- improve minecraft fps without changing gameplay
- optimize minecraft tick performance
- reduce lag on a modded minecraft server
- performance mod compatible with other mods
- speed up minecraft world ticking and entity updates

## When to choose
- you want better Minecraft performance with no gameplay or visual changes
- you need a drop-in optimization mod that works on client, server, or both
- you use Fabric or NeoForge and want broad mod compatibility
- you want a well-maintained, actively developed optimization mod

## When to avoid
- you want visual or graphics enhancements rather than engine optimizations
- you need a mod that changes game mechanics or adds features
- you play on a platform or mod loader other than Fabric or NeoForge
