PerfoBooster [1.20.1 - 1.21.8] - With Folia Support!

PerfoBooster delivers powerful server optimization through intelligent resource management, helping administrators maintain smooth gameplay even under heavy load.

Key Features:

• Aggressive Despawning: Automatically despawn configurable entity types (e.g., bats, experience orbs) far from players to reduce entity load, while protecting named entities.
• Farm Rate Limiter: Control animal breeding and mob spawner output per chunk to prevent entity overload from farms.
• Disable Mob AI: Freezes specified mob types in place by disabling their movement and behavior to reduce CPU usage while keeping them visually present.
• Inactive Chunk Unloader: Intelligently unloads chunks that are far from players and not actively used, freeing up server memory.
• Chunk Load Controller: Restricts plugins from loading new chunks synchronously, preventing potential lag spikes (configurable whitelist).
• Laggy Chunk Unloader: Identifies and unloads chunks exhibiting excessive tile entity update activity if no players are nearby.
• Hopper Optimizer: Fine-tunes hopper behavior with smart throttling for empty/full hoppers, global transfer-per-tick limits, and optional per-chunk hopper count limits.
• Adjust Spawner: Dynamically adjusts mob spawner settings (spawn count, delay, activation range, max nearby entities) based on TPS, light levels, and player proximity.
• Instant Leaf Decay: Accelerates leaf block removal when logs are broken or leaves naturally decay, preventing floating leaf blocks and reducing world clutter for improved performance.
• Max Explosion Yield: Limits the maximum yield/radius of explosions to prevent excessive damage, with entity-specific limits for TNT, Creepers, Fireballs, Wither Skulls, and End Crystals.
• Anti-Chain Explosions: Prevents chain reactions where explosions trigger other nearby explosions, with configurable radius and cooldown settings to stop TNT chains and block ignition.
• Deactivate Explosions: Completely disables explosions based on server performance or configuration, with TPS-based automatic deactivation and entity-specific controls.
• Player Redstone Anti-Spam: Prevents players from spamming redstone-interactive blocks, with configurable interaction limits and temporary blacklisting.
• Redstone Limiter: Prevents lag by limiting the total number of redstone components allowed within a radius, blocking placement and interactions when limits are exceeded.
• Automated Redstone Deactivation: Automatically disables all redstone activity server-wide when TPS drops below a threshold, then re-enables it when TPS recovers, with circuit breaker protection to prevent rapid on/off cycling.
• Automatic Garbage Collection: Triggers Java's garbage collection intelligently when memory usage exceeds configurable thresholds, helping to maintain stable memory.
• Dynamic View Distance Scaler: Automatically adjusts players' view distance based on current server TPS, reducing network and client-side load during lag.
• Idle Simulation Distance: Reduces simulation distance for idle players to lower server load while maintaining normal distance for active players.
• Software Optimizer (Experimental): Simple and powerful server configuration optimizer with three optimization levels (Conservative, Balanced, Aggressive). Intelligently optimizes 45+ settings across bukkit.yml, spigot.yml, and Paper configurations with automatic backup creation.

Recommendation Guide:

● Choose Conservative If:

• First time using server optimization
• Production server with strict uptime requirements
• Server with complex redstone contraptions or farms
• Want minimal risk and gradual optimization

● Choose Balanced If: (Recommended for 80% of servers)

• Want significant performance gains
• Can tolerate minor gameplay adjustments
• Most typical Minecraft servers
• Good balance of performance vs functionality

● Choose Aggressive If:

• Need maximum performance optimization
• High player count server with performance issues
• Can test thoroughly before production deployment
• Willing to adjust farms and builds if needed

MIGRATION PATH:

1. Start with Conservative - Test and monitor for 1-2 weeks
2. Upgrade to Balanced - If no issues, most servers stop here
3. Consider Aggressive - Only if maximum performance is needed

Remember: You can always restore from automatic backups if any level causes issues!
