FixLag: Performance without Compromise
FixLag is a lightweight but powerful performance suite for Paper, Purpur, and Spigot servers. While most lag-fix plugins simply delete items on a timer, FixLag uses Smart Analysis to keep your server running at a smooth 20 TPS without breaking your players' hard-earned farms.
🚀 Why choose FixLag?
- 🛠️ Actually Fixing Lag: The
/fixlag optimizeconfigcommand scans yourspigot.yml,bukkit.yml, andpaper.ymlto suggest better settings used by more experienced server admins. This prevents major sources of lag permanently. - ❌ No More Accidental Deletions: With the Retrieve GUI, players can recover items that were cleared during a cleanup. You can also whitelist custom-named items.
- 🧠 Reactive Scaling: Features like Dynamic Distance and Explosion Optimization only kick in when the server actually struggles. If your TPS is fine, FixLag stays out of the way.
- 📈 Staff Alerts: Get instant notifications if a player is creating an entity-lag machine or if RAM usage exceeds 90%.
✨ Feature Highlights
- Mob Stacking: Merges mobs into stacks to save CPU cycles.
- Chunk Analyzer: Instantly find which base or farm is causing the most entity lag.
- Smart Clear: Only clears entities when TPS drops below your target (e.g., 16.0).
- Detailed Stats: Beautifully formatted
/serverinfoand/gcinfocommands.
📋 Quick Start
- Drop the JAR into your
pluginsfolder. - Restart your server.
- Configure your preferences in
plugins/FixLag/config.yml. - Use
/serverinfoto check your current performance!
Permissions: FixLag uses standard permissions (e.g., fixlag.command, fixlag.serverinfo). All commands default to OP.
