Faban: it just works!
By Eric Reid-ISV Engineering-Oracle on Nov 30, 2007
While the Faban package and its web-based interface is quite useful, the fhb tool is especially handy for us in our Drupal testing -- it's command-line, Java-based and logs '90% response time' (not just average response time). It was used for our first, preliminary Drupal SAMP-vs-LAMP scaling tests, and we're planning to use it a lot more in the future (beware, Akara :)
Check out Faban, check out our testing results on the Drupal-on-Sun Wiki, and keep watching this space!
