Vista, both with and without SP1, performed notably slower than XP with SP3 in the test, taking over 80 seconds to complete the test, compared to the beta SP3-enhanced XP's 35 seconds. Vista's performance with the service pack increased less than 2 percent compared to performance without SP1--much lower than XP's SP3 improvement of 10 percent.
More details about the test at CNET's site. I'll think of this as Happy Holiday news for XP users -- putting the XP into Xmas, perhaps.
