I'm sorry but this is not true, at least for me. Performance are affected!!! Even if the virtual machine is in stand by the "Windows 7 (not responding)" process is around 5% CPU usage and sometimes it goes up over 100%.
Actually, these are likely 2 different problems and not related, I've also seen the not responding thing in activity monitor without seeing any impact whatsoever in VM performance.
From my own experience also, I've seen this sluggish behaviour as a result of installed hardware drivers on the Windows side, specifically in a bootcamp Windows XP VM I migrated to a virtual disk, after removing the Bootcamp and Logitech drivers the problem was solved.
