Window XP SP 3 outshines Vista SP 1 at twice the performance

After a long wait of Vista SP 1 two weeks ago. Devil Mountain Software, a Florida-based software development firm, reported that an upcoming update for Windows XP will offer substantial performance gains with their SP 3.

Running an Office productivity test suite on a preview version of Service Pack 3 for Windows XP, Devil Mountain discovered a 10 percent performance boost over the current version of Windows XP even though SP 3 was supposed to be mainly for bug fixes. So it turns out to be a great bonus for current XP users.

New tests have revealed that Windows XP with the beta Service Pack 3 has twice the performance of Vista, even with its long-awaited Service Pack 1.

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.


Windslash's comment:
Seems like Vista is still not doing so well despite the service pack upgrade, while XP surprisingly turns out to be even faster. And as both a Vista and XP user myself, I am greatly disappointed to how poorly Vista's performance is as compared to XP even though it did have some very nice interface and features
