Slower performance in Win7 compared to XP

why is my SW so slow? I am running an i7 with 4gb ram, windows7 home premium 64 bit, 1gb nvidia Geforce GT330M. I just installed SW2010...are there any setting I need to change to make it faster?

I was using SW2010 on an 3yr old XP machine and it ran decent speeds.

Any comments appreciated.
