Well I had a look at:
http://www.oracle.com/apps_benchmark/doc/E-Bus-R12-Pay_ORA_Med_IBM_p7-6-core-Single-Audited.pd
and
http://www.oracle.com/apps_benchmark/doc/E-Bus-R12-Pay_ORA_Med_HP_DL380-G6-Audited.pdf

I think it is a typo in the DL380 report. On page 3
"10,000 employees were processed in this test. Table 2 shows the processing time in minuts."
And then the table says 250.000 employees. It's a typo.

I don't agree. You can't just say that the numbers that doesn't suit you are suspicious. That is not fair.
And with regards to the notes about extrapolations then it comes from the fact that benchmark version's of V1.1 and higher has that disclaimer' the 1.0 which is the DL380 hasn't. Quite simple. Both benchmarks uses the same method for reporting.

Now what is the difference here is that the systems have a focus on making different parts of the benchmark run fast. That is the real difference.
And that isn't any different from a SPEC or TPC-C benchmark.

So I fail to see any foul play here, besides all the tuning parameters I can't understand why isn't set. Specially on the AIX, where I used to do a lot of system tuning quite a few years ago.
