Sorry for top posting.

Jason has more than a valid point. At least in former times, I do know that cut&paste from not only _identical_ configurations happened. For example, the system submitted to the list was equipped with eth NICs, whereas the performance quoted was from a similar system, but with a proprietary HPC interconnect. 

So much for the apples-to-apples.

I favour the SPEC suites when it comes to comparing systems, but with the caveat that vendors or customers of the larger system show little interrest.

Well, the terminology helps us to make sure we're comparing apples to
