Here are my results running Performance Test 7 in Windows 7 Home Edition 64b. These figures represent how Parallels scored using my Boot Camp partition for Windows 7 versus Boot Camp being booted natively. Parallels is running fullscreen and isolated from OSX. Macbook Pro 2010 (i7 2.66, 4GB, nvidia330(m)) CPU: 20% slower Memory: 30% slower 2D Graphics: 20% *faster* 3D Graphics: 30% slower Harddrive: 572% slower. Overall that is mighty impressive sans the harddrive performance. I'm not sure what is going on there but that is pretty terrible. Ideas? I have 8GB arriving this week. I will run the tests again when it's installed.
