Forget about Windows Vista. And forget about Windows Vista SP1. Microsoft's latest Windows client has been quite sluggish to begin with. This in both consumer adoption and in terms of the performance it delivers. As the operating system was crawling along, while performing the most common of tasks, even "speed bumps" seemed an integer part of the road's landscape. Right, that was uncalled for... But still, even on its best day, Vista is slow, and the first service pack for the operating system will change nothing in this aspect. Windows XP SP3 simply flies in comparison to Vista, SP1 or no SP1.
Benchmark testing delivered by the researchers at Devil Mountain Software, a software-development
company based in Florida, revealed that Windows XP SP3 is twice as fast as Windows Vista, with or without SP1 installed. The company threw the two operating systems one against the other on the following configuration: Dell XPS M1710, 2GHz Core 2 Duo CPU, 1GB of RAM and nVidia GeForce Go 7900GS video. While Vista SP1 delivered minor and disappointing growth in performance, XP SP3 faired quite well.
