Overview

NebulaBooster is a comprehensive server optimization plugin designed to dramatically improve your Minecraft server's performance. It intelligently manages entities, chunks, redstone mechanics, and items to maintain smooth gameplay even under heavy load.

Whether you're running a small survival server or a large network with hundreds of players, NebulaBooster adapts to your needs with highly configurable optimization systems.

Key Features

Entity Management System

• Smart Spawn Limiting - Per-chunk and per-world entity limits
• Hostile Mob Optimization - AI reduction based on distance from players
• Spawner Optimization - Dynamic delay adjustment and nearby entity limits
• Entity Culling - Intelligent removal of excess entities (oldest-first strategy)
• XP Farm Detection - Automatic detection and throttling of intensive farms
• Protected Entities - Never removes named mobs, pets, leashed entities, or bosses

Chunk Management System

• Load Optimization - Controls chunks loaded per tick
• Async Pre-generation - Pre-loads chunks ahead of flying players
• Activity Tracking - Monitors chunk activity levels (LOW/MEDIUM/HIGH/CRITICAL)
• Smart Unloading - Automatically unloads inactive chunks
• Spawn Protection - Keeps spawn chunks always loaded

Redstone Optimization System

• Update Throttling - Limits redstone updates per chunk/world
• Hopper Optimization - Transfer cooldowns and idle detection
• Clock Detection - Identifies and throttles redstone clocks
• Piston Limiting - Controls piston extensions per chunk
• Machine Detection - Alerts admins about lag-causing contraptions

Item Optimization System

• Smart Merging - Automatically merges nearby item stacks
• Scheduled Cleanup - Configurable cleanup intervals with warnings
• Projectile Limits - Per-player limits for snowballs, eggs, ender pearls
• Dupe Detection - Identifies suspicious item drop patterns
• Protected Items - Excludes valuable items from cleanup

Performance Monitoring

• Real-time TPS Tracking - Monitors server performance
• Memory Monitoring - Tracks RAM usage with alerts
• Emergency Mode - Automatic aggressive cleanup when TPS is critical
• Admin Alerts - Notifies staff of performance issues
• Detailed Statistics - View all metrics with /nebula stats

Large Servers (80+ players)

• Lower entity limits
• Aggressive chunk unloading
• Strict redstone throttling
• Enable emergency mode

Technical/Redstone Servers

• Increase redstone limits
• Disable clock detection
• Higher hopper limits
• Careful with piston limits
