Don't use it for actual benchmarking though, it has lots of known problems. Use something like: https://github.com/wg/wrk

What sort of issues does ab have?

[voidlogic]

Well the best thing would be to try it yourself. I have found:

   * ab has more results variation between runs
   * ab will almost always report lower performance than wrk
   * If you have two implementations being benchmarked, A and B and B is always faster than A. wrk will report a greater degree of performance separation between A and B.

These results are less noticeable the lower performance the site being benchmarked is.

ab takes more CPU time than a decent web server too.

wrk looks interesting. Have used http://tsung.erlang-projects.org/

How does it compare to Siege?
