It is not that certain that ramdisk on linux really helps.
ramdisk eat-up memory that cannot be used for fs-cache...
so ramdisk will increase the cache-miss at the kernel level...

ramdisk on Mac help tremendously because of how horrible HFS is lock-wise.

I have not tested ramdisk on Windows, so I do not know how effective it is.
