LagFixer helps improve server performance by optimizing the Minecraft engine.
While the paper itself is well optimized, some of its functions still require improvement.
It won’t fix all lag by itself, but it can noticeably reduce it when used alongside well coded plugins and a solid server setup.
It is not intended to resolve issues caused by low quality or poorly configured plugins.

- Java: 21 or later (use version 1.5.3 for java 8 support)
- Server: Bukkit/Spigot/Paper, hybrid Forge, etc.
