Now that this thread has bubbled back up to the top, you might also try
moving away from Apache Bench towards something else (my preferred HTTP
benchmarking tool is Faban, http://faban.sunsource.net/ , but that might
well be overkill). Apache Bench has request generation happening in a
single thread, so it's possible (and likely if you are just getting a
hello-world type page) that you are actually benchmarking how fast AB
can generate new requests to be served: Not what you are interested in.
