>>>>>I installed Virtual PC with Windows XP Mode on Windows 7 Pro 64. My experience is not very positive. It feels like a drunk/slow version of XP. For example, when I go to the command prompt and type any letter it takes about 5 seconds for the letter to appear. I installed the Virtual PC in order to possibly continue doing VFP9 support and development on the Win 7 64 PC. But not seem to be practical (at least after initial test). Has anybody had better experience with this?

>>How much RAM was allocated to the VM? You want to allocate enough for the VM to run but leave enough for the host computer to run reasonably well. Granted, it's not exactly the same situation as yours, but I've used VirtualPC on my 32-bit XP box to run DOS, Win95/98/Me and Win2K sessions w/o problem.

>I have not figured how to allocate more/some memory to the Virtual PC. But my issue is "why to have this PC and run everything in VM"? I might as well install Windows 7 32 bit and have - hopefully - decent speed and no headache with virtual PC. I would understand if I needed to run something in VM once in a while but it will be 90% of the time. You see what I am saying?

Since VirtualPC is running as an application on the host system, you need to make sure you've got enough RAM to run both the OS and the VM. To set the memory usage of the VM, go to the Virtual PC Console, then select the VM -- click on the settings button.

I understand what you're saying about questioning the sanity of running under emulation 90% of the time. I'm just pointing out that the VM shouldn't be running as slow as you're describing -- which makes me suspect that there is a configuration problem (allocated too much memory to VM -- resulting in frequent or nearly constant swap file use).

One of the reasons why I've been using VirtualPC is it gives me ability to have a test computer w/o actually having an extra computer. Granted it's slower than an actual PC -- but reconfiguring the computer for different test cases is much faster and easier. I keep a "baseline" harddisk image so that I can easily revert back to it after running various tests, so I'm able to always test starting from a "clean install" state.
