>> To test real 'real world' solutions, you need to give full freedom to the benchmarkee to build their own environment and an app the way they want it. You might be testing a LAMP stack compared to a LYME (Linux Yaws MySQL Erlang) stack, and there will be plenty of suggestions as to how to make one faster than the other.
>> The rabbit hole only gets deeper at each step. I do support the effort though. I think it would be better than microbenchmarks, although the tests would likely still not be reliable to judge on the performance of an application X.

Hmm... I never thought of it this way :) It sounds like a lot of work, but it would definitely be nice to arrive to something like that in the end.
