Anyone with an iMac G5 running VPC 7??

If so, how well does it run for just normal apps (MSN Messenger, MS Word)?

It ran horribly slow on mine. Mouse didn't even smoothly move across Windows window.

yes, I have VPC 7 (XP pro) running on my iMac. Max out the memory allocation to 512mb and the VRAM to 16mb and the performance for those things should be tolerable.

oh okay. and one more question - does the dock feature only work if it's the VPC XP or can it work if I install my own Windows 2000?

I ran win 2k and visual studios .net on my powerbook. Not the fastest thing in the world, but the mouse did move smoothly. I was able to complete my .net prgraming course with it.

If you use xp make sure to turn off all the eye candy.

HOLY MOLEY. XP on VPC sucks!! 2000 runs a lot better. I only really want it for MSN Messneger (until the new one for us comes out) and I have it just in case some if the programs that come with my textbooks are WIndows Only. Damn Business world - too windows-ish.

Actually this is the exact opposite of what you should do for the best VirtualPC performance with Windows as the client OS. Totally contrary to what you'd expect, it's far better to restrict the VPC virtual machine to just 256MB of RAM.

If you allocate a lot of memory to the virtual machine, Windows ends up allocating its own cache pools to cache files it's reading from the virtual disk image. This is, of course, in addition to the caching being done at the OS X level resulting in double-caching. Apparently this significantly harms performance.

Microsoft recommends allocating only 256MB of RAM to the virtual machine. 256MB is a magic number for Win2K or XP, the threshhold at which (and below) the Windows kernel runs in a lean, tight resources mode which doesn't do much of the caching that Windows will want to do if it thinks it has more RAM available.

While it seems nonsensical, it actually works out quite well. Even if the virtual machine thinks it's swapping to disk, that "swap file" ends up being cached in RAM at the OS X level and is much faster than it would be if Windows is allowed to grow into a larger memory footprint.

Also, if you're seeing sluggishness with mouse and window operations, make sure you're running the client-side drivers that Virtual PC expects. If you've installed from the VPC+XP bundle this is automatic, but if you installed from normal Windows XP install media, you'll need to install the VPC drivers after you've installed Windows. Neglecting this will result in sluggish mouse and video.

What's wrong with the MSN Messenger client for MacOS X?
