I'm running a Minecraft Craftbukkit server using this awesome script. My box has 3GB of RAM, and I have it set up to use 2GB minimum, and 2.5GB max.

I want to use the RAM-disk feature in the script, but I'm wondering how much space is needed for the RAM-disk to be effective? I've heard people get away with only using 200MB of RAM disk, and like 100MB of RAM for the server process, which seems sketchy...

Given I have 3GB of RAM available to me, any thoughts on RAM-disk size in comparison to just RAM?

P.S. Does this belong on Super User?
