Actually fixing lag instead of just clearing ground items.
FixLag is a modern, lightweight, and highly configurable Minecraft server optimization plugin. It goes beyond simple entity clearing by offering reactive lag prevention, mob stacking, detailed performance monitoring, and a unique safety net for accidental item deletions.
Automated Schedules: Configurable interval to remove ground items, arrows, and other entities to keep your server clean.
Reactive "Smart Clear": Automatically triggers an emergency cleanup if the server TPS (Ticks Per Second) drops below a defined threshold (e.g., 16.0 TPS).
Customizable Whitelists: Fully control which entities are removed and which are ignored.
Name Tag Protection: Automatically ignores items or mobs that have been renamed (via Anvil or Name Tag) to protect player valuables.
Safety Net: Did the cleaner run while someone dropped some valuables on the ground? You don't have to be annoyed by these support tickets again!
GUI Retrieval: Use /fixlag retrieve to open a GUI and recover items deleted in the last cleanup.
Auto-Expiry: The recovery chest automatically clears itself after a short period to prevent memory leaks.
Performance Boost: Automatically stacks nearby mobs of the same type to drastically reduce entity counts without affecting gameplay rates.
Seamless Integration: Mobs unstack one by one upon death.
Visual Indicators: Customizable display names show stack sizes (e.g., Zombie x5).
Server Info: Get real-time stats including TPS (1m, 5m, 15m), RAM usage, CPU load, and average ping with /serverinfo.
Garbage Collection: View detailed JVM memory and Garbage Collector statistics via /gcinfo to diagnose deeper performance issues.
Proactive Warnings: Detects when a specific area or player has an abnormal amount of entities nearby.
Staff Alerts: Notifies online staff members of potential lag sources so they can investigate before the server crashes.
