But there is only so much increasing on both sides that you can do, much
less just the OS400 job side. At some point increasing OS400 jobs will only
slow things down because the ones currently running are waiting in line for
their time-slice. At one point I think we had a couple hundred Apache jobs
running and that still wasn't enough to keep up with JMeter on a powerful
desktop spawning multiple hundreds of threads at a time. Note that I put
together a very simple write-to-standard-out CGI program for these test to
insure there was very little time spent in the OS400 job.
At least you got to where it is the "whole system" that is the bottleneck and not just a single component :)

If I understood you correctly you describe a situation where you put load on Apache and each request invokes a dead simple AS/400 job?

That is a good scenario to optimize :) What did you find help?
