It would be nice if you could add measurements for recent Marvell 
products there, such as the Kirkwood (think SheevaPlug or the like 
running at 1.2 GHz), or Dove.  I wold expect memory throughput on those 
to be quite good.

Also, your article is completely missing on the other metric which is 
power consumption.  After all what would be most interesting is not the 
various performance numbers per MHz but those performance numbers per 
Watt.
