Re: [users@httpd] Restricting number of child processes in Worker MPM

[apacheuser123@xxxxxxx]

Thanks Joshua. I am trying to make sure there is exactly one memory cache per box. Guess your explanation means that I am achieving that with the config I posted ?

Also, would setting the ThreadsPerChild to 150 cause performance issues( I am running Apache on Red hat) or is 150 a OK value ?

Thanks again..

The extra child is probably the CGI daemon used for launching CGI scripts.
