I have a winXP virtual PC running on a powerful win7 x64 (4 cores 8Gb RAM) workstation.
When I'm copying files in the virtual PC, from my workstation
(\\<my computer name>\c$\etc.)
to the virtual, it goes extremely slow even for a 500kb file.
I can, on the other hand, copy (in or out) a 10mb file to a network resource in just a few seconds.
Any idea why this might happen?
