Overview
DynRegionPerf is a sophisticated performance optimization plugin that dynamically manages chunks and regions based on player density to maintain stable TPS/MSPT. It uses advanced clustering algorithms, adaptive control systems, and regional entity management to optimize server performance.

Features
️ Density Mapping & Clustering

• Grid-based Analysis: Maps players to 64×64 block grids every 2 seconds
• BFS Clustering: Groups nearby high-density cells into "hot regions"
• Dynamic Classification: Automatically categorizes regions as hot/normal/cold

Dynamic View Distance

• Adaptive Adjustment: Automatically adjusts view distance based on region temperature
• Performance Scaling: Reduces view distance during poor performance
• Player-specific: Individual view distance management per player

Chunk Budget Management

• Predictive Loading: Preloads chunks based on player movement patterns
• Budget Allocation: Allocates chunk loading budget per hot region (FPS optimized)
• Priority System: Loads chunks closer to players first
• Rate Limiting: Limits chunk loads per tick to prevent FPS drops
• Aggressive Unloading: Unloads unused chunks in cold regions

Regional Entity Controls

• Entity Limits: Applies different entity caps for hot/cold regions
• Smart Despawning: Removes distant entities in cold regions
• Random Tick Scaling: Adjusts random tick rates based on region temperature

️ Adaptive Control System

• PID-lite Controller: Uses simplified PID control for MSPT/TPS management
• Gradual Adjustments: Makes incremental changes to avoid instability
• Emergency Measures: Applies aggressive optimizations during poor performance

Comprehensive Metrics

• Real-time Monitoring: Tracks TPS, MSPT, loaded chunks, and hot regions
• Rolling Data Storage: Saves 5-minute rolling averages to JSON
• bStats Integration: Anonymous usage statistics (temporarily disabled)
