In Win 7 I have one app that uses everything it can find so when it's running all 4 processors are 100% utilized. In Linux I see the CPU usage at 33%. Win 7 is sluggish when this app is running as it hogs from the system In VMWare Player I'm running Win XP VMs with 2 processors. None of my apps in XP use more than 1 processor. XP itself is quite responsive even when these apps are using 1 of the 2 processors dedicated the the VM. I seldom run more than 1 app in any Windows VM as I don't trust Windows. I've not had any problems with any of these VMs that I'd associate with using multiple cores. And yes, I do own these Windows licenses. VMs keep that money useful until some day some Linux apps come along that do what these do for me in Windows. - Mark
