According to Infoworld.
"In every test we performed on systems with a single CPU, OfficeBench ran in less time under Windows 2000 than under Windows XP. The differences ranged from slight to dramatic, depending on the hardware configuration, but XP was always slower."
I have to say that, after running it for the last couple of months,it does seem pretty sluggish.
