Ultimate Performance Optimization Engine for Minecraft Servers

Advanced lag reduction, automatic cleanup systems, mob optimization, TPS monitoring, smart entity management, redstone lag prevention, Bedrock GUI support, and real-time server performance tools.

Overview

UltClearLagg is a complete server optimization plugin built for modern Minecraft servers running Paper/Purpur 1.21+.

Unlike basic clear lag plugins that only remove ground items, UltClearLagg provides a modular optimization system that includes:

  • Bedrock GUI compatibility
  • ActionBar + BossBar notifications
  • Performance dashboards
  • AI freezing during low TPS situations

The plugin protects important entities such as:

  • Named mobs
  • Villagers
  • Tamed pets
  • Valuable items
  • Important worlds
