Windows Vista SP1 is really an improvement!

A few nights ago I spent a lot of time on doing some performance tests about Windows Vista Service Pack 1 for publishing in a magazine. I compared several areas such as copying files from hard drive to another hard drive as well as over both wired and wireless networks. I also ran benchmarking tests with 3DMark06 and PCMark05 as well as the FPS-test in Half-Life 2 Lost Coast and finally I compared extracting files from a zip file. I can just say that Vista with SP1 out-performed Vista RTM in all tests, in some tests by far! This is very promising for the final release but on the other hand it is also a sign of the fact that maybe Vista wasn’t so ready to be released in November last year after all?

Anyway, in the test of copying files over the wired network the time it took with Vista RTM was 4 minutes and 4 seconds and with Vista SP1 it was 3 minutes and 9 seconds, quite an improvement. Extracting the files with Vista RTM took 2 minutes and 12 seconds while it just took 1 minute and 25 seconds with Vista SP1. Maybe I ought to run the same tests on my XP installation on the same machine, but do we dare to see that result?
