Depending on which benchmarks. Benchmarks depend a lot on specific configuration, drivers, etc. You can find benchmakrs where XP/Vista/7 each beat the competition.FredGarvin wrote:Interesting, if you go by the benchmarks, XP usually scores better.
But benchmarks in general don't mean much. What matters for the average users is the responsiveness of the system. When preparing for Win7, Microsoft learned from the various complaints of users on the responsiveness of Vista, and conducted lots of research, and performance tracking in typical real-life scenarios to optimize it for Win7. These things probably do make some difference.
Then again, whenever most users say "I installed X and immediately noticed a tremendous improvement over Y", they usually don't account for differences between a freshly installed OS and a OS that has been somewhat bogged down by a history of software/hardware installation/deinstallation. Typically, a fresh installation will perform faster.
