Because you started off admitting that you were doing an "apples to apples" versus "apples to oranges" comparison.
I'd still like to see a true "apples to apples" comparison between the boxes: ONLY the same job running ( so the cpu(s) aren't giving cycles to other apps ), break the files up to equivalent sizes ( to overcome the limitations on a single file size on the mainframe - guess IBM shoulda known several years ago that people want to have files over 50 gig in size ), the code as identical as possible, hardware optimized in as similar a configuration, and then drop the starter flag and let 'em go.
