Use RAM disks for a VirtualPC speed gain
This hint is not going to speed up the operation of VPC (or any other application) at all. The only reason it seems to speed up things is because in the process of opening the ram-disk you cause everything to be loaded into memory already. MacOS X's virtual memory system works like a ram-disk until you change something... it caches the reads from the disk, and until it needs that space in memory (with a complicated system for prioritizing things) it does not page it out to disk. People used ram-disks in MacOS 9 because this advanced system did not exist. It was a way of simulating it for special cases. This hint simply shows that most people don't understand how the virtual memory system works on MacOS X.
