How many php-cgi threads? - Keirnan - 02-10-2009 04:43 AM

I have ISPCP RC7 on Ubuntu 8. The Apache and PHP configurations are all just how ISPCP left them. I have made no changes to them. I know very little about the various PHP configurations (cgi, fast-cgi, etc).

Right now, I have a lot of php-cgi processes running, as you can see below. Some of them are using significant resources.

My question is how many of those should I have? Is this normal? I thought it would only launch like 5 at the most.
