InfoWorld says WinXP much slower than Win2K

iforgotmyfirstlogon submitted an InfoWorld story that makes the shocking claim that XP is slower then 2k for business use. Pretty graphs, comparisons of SMP, and they even tested without the eye candy. My favorite comment is this one "it appears that for light-duty service on the newest hardware, Windows XP with Office XP is an acceptable choice -- if an 11 percent performance hit, or 53 minutes added to an 8-hour day, is acceptable." And thats the best case scenario.
