This may just be my ignorance about Windows XP. I'm running Parallels Build 1848 on a MacBook Pro with 2 gb RAM. The Windows Task Manager shows only one processor running. I ran the Intel Processor Frequency ID Utility, and here is what is shows: The reason I am concerned is this: I had been satisfied with my Windows performance on a subjective level. Then a friend gave me a large spreadsheet that he uses to benchmark laptops. While his AMD laptop recalculated the Excel sheet in 5:30, it took me over 8 minutes on my MacBook Pro. This is quite disappointing - but I thought it might have to do with no using the other core... is that possible? Thanks. Sam V.
You are correct - guest OS in VM uses only 1 core. The second core is left for Mac OS X and other VMs.
