A quick question...

I just got Win7 Pro 64bit up and running as a VM within Fusion 5 on my MacPro. By default the installation allocated 1 processor and 2GB of RAM. My '08 MacPro is an 8 core machine with 12GB of RAM. Will I see any performance increase by allocating another processor and 2GB of RAM?

Possibly, yes. 2 cores and 4GB of RAM should help. Unless you have a reason, do not go over 4 cores for the VM. The way VMs work with multi cores is that all cores will néed to be available at the same tie (not used by host OS) to process a task. If one is not available, the VM can stall (although not long) to process the task.

Try and test your settings. I can't hurt anything and you can reverse it if it slows down your host OS.
