Analysis: Server Side Java energy efficiency versus load

With the arrival of the latest standardized energy efficiency benchmark from SPEC, we have a good way to measure server efficiency.  In light of the recent controversy over flawed energy efficiency studies that have unfortunately been touted by so many in the press instead of SPEC, I thought I'd offer some more in-depth analysis...

Beware of flawed CPU efficiency study

Update 2/22/2008 - I originally used the word "rigged" to describe Neal Nelson's study. My reasoning for using the word "rigged" was due to the fact that the test platforms used in Nelson's study painted an inaccurate picture. Nelson's study omitted two generations of Intel products while including...

SPEC launches standardized energy efficiency benchmarkGreat Article, George.Validates what has been known for some time now. No need for any more made up metrics like ACP or other nonsense.Why are there no AMD fans posting? Could it be because Intel owns the power/perf crown?Yeah, I thought so.Why did SPEC agree...
