I was thinking about doing this awhile back. I made a ramdisk and used both
bonnie and bonnie2 to do some benchmarking on it, and I actually got worse
performance on the Ramdisk. You still have the overhead of the file system,
and you have no hardware DMA controller with a Ramdisk. It was slower in my
experience.
The box I tested it on had 1GB of Ram, and a 512MB ramdisk. No swap was
being used during the tests.
