Patriot reportedly found Windows 2000 to be "5% to 8% faster" than OSes like Windows XP, Windows Vista, Mac OS X, and Linux, although the report doesn't say exactly what tests those numbers apply to. Patriot Engineering Manager Saeed Arash Far commented that Vista actually outperformed XP in the same benchmarks, but Windows 2000 trumped them both.
