I was hoping to see a better comparison between their performances. I don't see any use for comparing the two based on their 'openness' as we all know windows is closed source and linux is not so that comparison doesn't give us (at least me) any useful information.
Are the colors supposed to be indicative of something? is red bad and green good?
Also, for the multiprocessor limits in windows, I highly doubt they are kernel limits. They are imposed by the different flavors of the high-level OS.
The most useful bit in that comparison was about the scheduler
