Apache Worker vs Prefork

[kljuka]

First, I would like to congratulate the ispCP team for building such a promising product. Unfortunately I don't know whether it fits my needs:

I have an Ubuntu 9.10 (soon to be 10.04) server with LAMP instalation (Apache 2.2: apache2-mpm-prefork, Php: libapache2-mod-php5, ...).

Whey I try to install apache2-mpm-worker, the system automatically removes some programs (Phpmyadmin, Cacti - I need them to monitor my server and for database management).

Do you have any experience with installing ispCP using Apache 2 Prefork and PHP5 module (not as fast-cgi) in Ubuntu? Or some other suggestions?

Thank you for your help
