Somehow I'm not surprised that comments section is disabled in this example of IBM's Black Magic. I won't comment on it myself as there is no point in repeating Joerg arguments - I agree with him in 100%. This is about recent world record in TPC-C benchmark from Oracle/Sun.
However I would like to suggest to Ms. Stahl that there is another big advantage in IBM's setup she's missed - not only IBM did more tpmC/core but they also did:
larger number or racks per tpmC
larger power usage/tpmC
I think that somehow most customers would consider above three as more important than tpmC/core (assuming they would consider TPC-C relevant in the first place).
