ChunkOptimizer Advanced Chunk Caching and Management Plugin

JAVA 11+

Introduction
Welcome to ChunkOptimizer, the ultimate plugin for improving the performance of your Minecraft server by optimizing chunk loading and caching. Whether you're running a small server for friends or managing a bustling public server, ChunkOptimizer ensures efficient chunk management to minimize lag and maximize performance.

Features
Advanced Chunk Caching:
Reduces the load on your server by caching frequently accessed chunks.
Automatically manages cache size to prevent memory overuse.

Configurable Cleanup System:
Cleans up unused chunks based on idle time, server load, and configurable batch sizes.
Prevents performance drops even during peak player activity.

Dynamic Optimization:
Automatically adjusts cleanup strategies based on server performance metrics (e.g., tick time).

Multi-World Support:
Select which worlds to optimize (e.g., overworld, nether, end).

SQLite Integration:
Saves and loads chunk data efficiently using an embedded SQLite database.

Why Use ChunkOptimizer?
Chunk loading and unloading are some of the most resource-intensive tasks in a Minecraft server. ChunkOptimizer:
- Reduces server strain during high player counts.
- Prevents frequent reloading of the same chunks.
- Improves TPS (ticks per second) by removing unnecessary background tasks.
- Provides fine-grained control over chunk caching and cleanup.

Configuration
ChunkOptimizer is fully customizable through its config.yml file. Here’s an example configuration:

# Cache Configuration

cache:
  # Maximum number of chunks stored in the cache.
  # Recommended settings based on server size:
  # - Small servers (1-10 players): 500 chunks (~256MB additional RAM).
  # - Medium servers (10-50 players): 2000 chunks (~1GB additional RAM).
  # - Large servers (50+ players): 5000 chunks (~2.5GB additional RAM).
  max-size: 2000

  # Batch size for cleanup tasks.
  # Reduce this value if the plugin causes lag under high player counts.
  clean-batch-size: 100

  # Maximum idle time (in milliseconds) before removing a chunk from the cache.
  # For example: 60000 ms = 1 minute.
  max-idle-time: 60000

# Worlds Optimization
optimize-worlds:
  # Specify which worlds to optimize.
  world: true
  nether: false
  the_end: false

Installation

1. Place the ChunkOptimizer.jar file in your server's plugins folder.
2. Start your server to generate the default configuration file.
3. Customize the config.yml to suit your server’s needs.
4. Restart the server to apply changes.
