🛠️ 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 optimizeconfig command scans your spigot.yml, bukkit.yml, and paper.yml to 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 /serverinfo and /gcinfo commands.

📋 Quick Start

  1. Drop the JAR into your plugins folder.
  2. Restart your server.
  3. Configure your preferences in plugins/FixLag/config.yml.
  4. Use /serverinfo to check your current performance!

Permissions: FixLag uses standard permissions (e.g., fixlag.command, fixlag.serverinfo). All commands default to OP.

patched the following bugs on the Mojang bug tracker: MC-153831, MC-306840, MC-311414, and MC-263882. Also note that the fix to MC-263882 is not a real 'fix'. To fix it will require either NMS patching (dangerous) or patching Paper/purpur (not my job here). The mitigation done for MC-263882 is simply to cap TNT speeds. This may or may not affect TNT cannon builds.
