This benchmark is available on www.sciviews.org, a site dedicated to the distribution of various open source (free) scientific software. Please refer to this website to have more details about tests.
The tests were run 50 times and the mean value is recorded. See results to appreciate the improvements of the new Windows version 4.0.
