Use RAM disks for a VirtualPC speed gain
Authored by: pbw on Oct 05, '04 06:51:57PM

First, how much total RAM do you have?

I don't fully understand OS X's memory management but I was under the impression that OS X RAM disks can "lose performance" if they get swapped out by virtual memory. In other words, could the RAM disk essentially get written to disk? And if so, could that make performance worse or would it just make it no different than running VPC normally (not in a RAM disk)?

I am much more interested in trying to run the app and VPC disk in RAM for max performance. However, I have a feeling that I would need more than 2 times the amount of RAM compared with the RAM disk size (e.g. 1+ GB RAM for 500 MB RAM disk). I don't have VPC7 to test this out...
