Eliminating the Primary Cause of Lag

In the Minecraft engine, real-time world generation is the most CPU-intensive task your server will perform. As players explore new territories, the server must calculate complex biome distributions, ore deposits, and structural placement instantly. This frequently results in significant Ticks Per Second (TPS) drops and micro-stutters. By Pre-Generating your world, you calculate these assets once and store them on your high-speed NVMe disk, effectively turning heavy mathematical processing into a simple file read. The Chunky plugin is the industry-standard tool for managing this process efficiently.

Installation & Strategic Planning

Follow these steps to deploy the Chunky framework on your Paper, Spigot, or Purpur server.
1

Acquire Latest Build

Download the appropriate JAR file from the official Chunky Hangar Repository.
2

Deploy to Plugins

Using the Game Panel File Manager, upload the JAR into your server’s /plugins/ directory.
3

Initialize Environment

Restart your server. Chunky will automatically generate its configuration folders.
4

Define Your Boundary

A 5,000-block radius (10,000 x 10,000 total area) is generally sufficient for medium communities. Note that area increases exponentially; a 10k radius is technically 4x larger than a 5k radius and will require significantly more storage.

​
Operational Workflow

Execute the following commands in sequence within your server console to begin the generation process.
  1. /chunky radius 5000: Defines the physical boundary of the render.
  2. /chunky center 0 0: Centers the generation point on the world origin (spawn).
  3. /chunky start: Initializes the background generation process.

​
Technical Performance Impact

While active, Chunky is designed to use 100% of available CPU resources to complete the render as quickly as possible. During this window, legitimate gameplay will be severely impacted. We strongly recommend scheduling world generation during Off-Peak Hours when zero players are online.
Pre-generated chunks are stored physically on your server. A standard 10k radius world can consume between 10GB and 25GB of disk space depending on your Minecraft version and world complexity. Ensure you have adequate storage on your FREAKHOSTING plan before initiating a large-scale render.

​
Nether & End Synchronization

Exploration lag is just as prevalent in secondary dimensions. We highly recommend pre-generating at least a 2,000-block radius in the Nether using the command: /chunky world world_nether followed by your radius and start commands.
