- Create a RAM disk just big enough to copy Virtual PC application then launch VirtualPC from the RAM disk. There's noticeable performance gain. All of your changes are saved on the Virtual PC Disk, so it doesn't matter if Virtual PC application gets deleted off of the RAM disk.
- You can REALLY get a huge performance gain if your VirtualPC disk is small. If you are running Windows 95 or NT, then the VirtualPC disk size is around 200megs, and you can copy the application and the disk into the RAM disk. This is real performance boost. Just remember to copy back the PC disk to your hard drive before ejecting RAM disk!Otherwise, your data will not be saved!
[robg adds: A previous hint discussed RAM relative to web browsing, and this much older hint covers methods of creating RAM disks yourself without any third party software. I don't have VirtualPC yet, so I can't confirm any speed boost from this technique.]
