Obviously if you have more than one CPU and assign more than one to VMWare it's going to run better ;) I meant that the feature to drop down to one CPU is just so that you can test single CPU code.

My Windows XP guest has two CPUs assigned to it, and it appears* to perform better with two rather than one. Hmm, I’m not sure you’re correct.

This is because VMWare isn't an emulator. I think you're getting confused with something else there. And this feature is just so that you can run two VMs, each set to one CPU, on a dual CPU machine, and hopefully have better performance.
