yow!  I think it's fair to say that Apple has some work to do.
I suppose it's also possible that the OS is tuned for models
(such as desktop ones, perhaps with different cpu/cache/dram configs.)

does OS X have page coloring inherited from *BSD?  perhaps that 
explains the only place it comes out ahead (memory bandwidth/latency).
