I am told the Web 2.0 data centers have written much of their own code and done it for 64-bit data sets, but some enterprise Web server and other systems can squeak by on 32-bit code.
I believe there may be some third-party benchmarks f0or Calxeda out today. Anyone see them?
64b for them makes sense. Any idea on whether customers are signing up for the 32b processors.
The power measurement charts like the one in the article is questionable. It does not mention the performance or what workload was running on the webserver e.g. The ECX-1000 is low power - that is a given but what performance does it get?
Charts such as these make them lose credibility.
