Apache running PHP and PERL webapps performance tuning

I have a Centos 5 server running Apache webserver. The majority of webapplications running on the server are AMP applications however there is one application that is running PERL. The application is OTRS. The OTRS application is not performing as fast as we would like. The PHP applications are all fine. My initial suspisions are that mod_perl is not configured properly. I need someone who is well versed in finding bottle necks in Apache configurations/mod_perl/perl applications. I will send [login to view URL] etc in private messaging here on RAC and might give full remote access to the server or run the session in a webmeeting. The goal is to get all page loads in OTRS sub 2 seconds. (There is currently no data in the database so this is not an issue of indexes ...)
