A tmpfs mount will use your Virtual Memory as required, which will be RAM as well as Swap, so in a heavily loaded system it could well be using disk space.

Using /tmp in this manner can certainly improve "performance", but it also can cause issues in things like DVD creation if a temporary image file (~8GB) happens to be created in that folder.....
Do you know how to setup a real ramdisk?
