How do I pre-generate a Minecraft world?

I want to create a new world on our Minecraft server, but exploring a new map and generating terrain causes massive lag.

Is there a way to pre generate the chunks (with the default map generator) in a specific radius around the spawn?

I’m looking for a Bukkit plugin or tool I can use on our Linux machine. An offline tool I can run on my local machine is ok, too.


In this thread on Reddit, I found a command line script that will generate terrain by repeatedly restarting a server with varying spawn points until the area you specify is filled. This seems like just what you’re looking for.

There’s also a Bukkit plugin named WorldGenerationControl which can do it on a live server.
