Re: [users@httpd] Connection Reset

HI Steve,
I'm using a script called AutoBench.
This software does benchmark distributed.
This is the site: http://www.xenoclast.org/autobench/
My web cluster has power servers (Quad Core, 2GB RAM) and I think that they
support that workload.
My web site is a PHP page and it does only a "loop for" until 20000.
Thank you
Ricardo

Hi Ricardo,
I found when I was doing my tests with httperf, I had to use multiple
computers to do proper load testing because HTTPERF couldn't handle sending
so many simultaneous connections. Through trail and error the best results I
got was using only ~400 simultaneous requests firing from the software. Then
I multiplied that same load test over many computers.
