Minecraft reads and writes a lot from disk. In order to speed this up we can store the files in memory instead. If you google “minecraft tmpfs” you will find a lot of info on this.

The main issue is that ramdisks created using tmpfs are temporary. The content is wiped on a system reboot.

The script I created takes care of persisting the ramdisk. It is a general solution that can be used for any content. Minecraft servers included.

OR you could just move your whole server there 🙂 That way you won’t need to mess with symbolic links at all. If you are using the dynmap plugin you should configure so the rendered tiles are stored elsewhere. Because all those images can easily reach over 10 gigabytes.
