Re: Apache Optimization

But that just starts 30 CGI threads as far as I can see.

Earlier in this thread it was stated that "If you had Apache set to launch 30 jobs and ThreadsPerChild set to 100, you could handle 3000 concurrent connections."

Are you saying that if you have
StartCGI 30
ThreadsPerChild 100

You will get 3000 CGI threads?

I am not "getting" this differentiation between a job and a CGI thread. Maybe I am being dense.

To start 30 CGI jobs, you would need this in your httpd.conf file:
StartCGI 30

Thanks,

I have read that before, but it doesn't relate (at least not in my mind) to what I actually see on the IBMi in the QHHTPSVR subsystem.

You said "If you had Apache set to launch 30 jobs and ThreadsPerChild set to 100, you could handle 3000 concurrent connections."



If threadsperchild dictates the number of connections that can be serviced in a job, which one of these is the job to which you allude? The only BATCHI job that appears multiple times are the ones calling QZSRCGI, so one must assume that they are threads - so which job are they a thread of, and how can one start 30 of them?

If you had Apache set to launch 30 jobs and ThreadsPerChild set to

100, you could handle 3000 concurrent connections.



That sounds interesting, Dean. What are the configuration directives for launching 30 jobs?
