Joe,
You will probably need more info, but if you have time give it a try and
if you run into problems we could contact greg ames from the ASF.
Thanks,
JJ

In our testing RH3 was horrible -- worse than 2.1. However, a system
with a stock 2.6 kernel with glic2.3.3 with nptl performed comfortable
better than 2.1
YMMV

Thanks for posting these measurements. I was happy to see that performance
stays pretty flat as the system got overloaded. The AS 3.0 8 CPU curve
What did you use for ThreadsPerChild? The default?
yes we used the default values for the worker threading model.
I'm very curious to know why prefork is beating worker. Could you get a profile of the CPU usage for both cases? I've had good luck with oprofile. I had a little trouble compiling

Apache is servicing more requests per sec on 2.1 on 1 and 2 CPUs, 3.0

HyperThreading enabled or not when limited to 1/2 CPUs, if these are HTCPUs? That can make a difference (either way) when benchmarking IIRC.
CPUs are not HT.
1. What was the CPU utilization during the tests
2. What size of file was being benched?

1. What was the CPU utilization during the tests
I think CPU utilization is above 90% during the test,
at least on my 4 CPUs box, which is not the one used to
gather the submitted results. I could find out but will be
delighted to have more details on what you are exactly
looking for based on

Prefork still serving static requests faster than worker
