In all howto's, prefork preferred over worker?
At least all Debian/Ubuntu guides seems to favor apache prefork over worker. Why the guides do not instruct to use worker and PHP5 with FCGI, or at least include it as an option?
Shouldn't web server receive a noticeable performance increase by using worker and PHP on FCGI?
From what I gather, to make PHP5 run on FCGI all what is necessary is to drop libapache2-mod-php5. No other changes in the guides is needed as ISPConfig handles setting up virtualhosts. Correct?
