Pre-generating Your World with Chunky
A lot of server lag comes from generating new terrain: whenever a player walks into unexplored chunks, the server has to create them on the spot. Chunky solves this by generating your world ahead of time, so exploration becomes smooth and lag-free.
Chunky is available as both a plugin (Spigot/Paper) and a mod (Fabric/Forge). Install the version that matches your server software and restart.
Generating Your World
- Set the world you want to generate (defaults to the world you're in):
/chunky world <world-name> - Set the center point of the generation, usually your spawn:
/chunky center 0 0 - Set how far out to generate, in blocks from the center:
/chunky radius 5000 - Start the task:
/chunky start
Monitoring & Controlling
| Command | What it does |
|---|---|
/chunky progress | Shows how far along the generation is. |
/chunky pause | Pauses the current task. |
/chunky continue | Resumes a paused task. |
/chunky cancel | Stops the task entirely. |
tip
Pre-generation is CPU-intensive, so it's best done while few or no players are online. Match your radius to the world border you plan to use, as there's no need to generate terrain players will never reach.
