LessLag is a performance optimization plugin for Minecraft servers that reduces lag automatically by controlling worlds, entities, redstone, mob AI, and much more. Designed to keep TPS high without sacrificing gameplay.

💡 About

LessLag dynamically monitors server performance and automatically disables or throttles lag-inducing features. From unloading inactive worlds to merging dropped items, disabling redstone during TPS drops, and controlling entity AI—LessLag keeps your server smooth with minimal change of vanilla features.

**Requires Protocol Lib to work!**
