   Hmm, I don't agree. Mem transfer and CPU speed also increased. The ratio is   
   better,   
   but not much.   
      
   However I miss "cache utilization" in this story.  Often people try to max   
   the cache unnecessarily, since a small part already gives 95% of the   
   performance advantage.
