Vista SP1 faster, but not as fast as XP
Those stuck with...er, using Windows Vista have anxiously awaited the speed-up promised by the release of Vista's Service Pack 1. While preliminary reports suggest measurable speed increases over the original release of Vista, recent benchmarking of Vista SP1 against Windows XP SP2 shows that XP performs better.
As concluded by Adrian Kingsley-Hughes in his blog on ZDNet after running a series of benchmark tests on the two operating systems:
Looking at the data there’s only one conclusion that can be drawn - Windows XP SP2 is faster than Windows Vista SP1. End of story. Out of the fifteen tests carried out, XP SP2 beat Vista SP1 in eleven, Vista SP1 beat XP SP2 in two of the tests, and two of the tests resulted in a draw.
The best result for Vista SP1 was in the single file drive-to-drive copy, while the best result for XP SP2 was extracting multiple files from a compressed folder. Given these results and taking into account the improvements that SP1 bought to Vista, if I was to go back and compare XP SP2 with Vista RTM, XP would have hammered Vista even harder.
Kingsley-Hughes promised to continue benchmarking Vista and XP to uncover the reasons behind this performance difference.
In the meantime, a movement of sorts has sprung up to persuade Microsoft not to kill new sales of Windows XP as scheduled on June 30, 2008. There is an on-line petition where XP users can voice their opinion that XP be kept alive for purchase.
