According to those who have got their hands on betas of SP3 for XP and SP1 for Vista, there is no noticeable improvement to speed with Vista SP1, while XP SP3 gives roughly a 10% speed boost. Allegedly.
If this turns out to be the case when the patches are released, then it is rather ironic that Vista, with its reputation for being a tortoise of an OS, is not getting a much needed performance boost. XP on the other hand, hardly needs it.
We at PC Plus will reserve judgement until the final thing is in our hands.
