Have a look at http://homepage.mac.com/svc/DW-Bench
The idea is to use paserve to serve either a static or a dynamic page
and then exercise the server using the apache benchmarking tool ab. You
do not really need KPAX to set this test up. Pushing up the -n and -c
parameters might tell you something about scaleability or how well the
dual processor machine utilizes its resources.

This is a though one: I always said that it was our intention to make
KPAX open source and publish it since it is based on a lot of great
open source projects. Many people have asked for it.
And although KPAX has been used in two production projects and one
student thesis over the course of more than one year, the code isn't
that clean. Up until last month it even had quite a lot of file system
Doing open source is a lot more difficult than just putting the source
code online. And I know that (1) I don't think KPAX is good enough and
(2) I don't want to keep supporting KPAX. As a matter of fact, I am
planning a newer version of KPAX for the very near future.
What I want to try is to make an as-is snapshot release for those
interested with lots of disclaimers, when I find some more time.
