Ab is not very good for testing concurrency. Check out flood for somewhat better concurrency (http://httpd.apache.org/test/flood/). Also, keep in mind that although you'll see better scalability with the worker MPM over the "classic" prefork MPM, the biggest improvement will be in memory requirements. I've run 300+ threads on my solaris 8 box while only consuming around 20MB. -aaron
