One of the variations that is being tested here, that I'm not sure if it is legitimate is that for PHP specifically, Apache is likely spinning out many PHP threads, I'm not sure if the same behavior is happening on the ruby side. Thus, if you are comparing performance of 10 PHP threads to 1 ruby or python thread, your benchmark is not going to be terribly accurate.
