I guess that's because Catalyst loads once and then stays loaded and handle 
your clients requests until you restart your server.

Sooner or later you will use all your modules, then why not load it all at 
once instead of using extra time on loading it later?

A normal "mistake" of managing web servers these days is to put tons of web 
applications onto one server and letting them fight over resources. Servers 
(and memory in particular) is a low cost factor (compared to development 
costs). Then why not give your lovely web application some GB's of memory?
