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
I cannot understand why the high C proportion is considered "good"; while it is (still) unusual to write kernels in languages other than C and there is a good reason for it, it does not necessarily mean that a kernel not in C is inferior to a kernel in C. How about BeOS and Haiku, for example?
Windows licensing as of (don't remember, either Vista or 7) considers sockets as its unit of measure, so you'll never end up running with half the cores on your CPU disabled.
