newbie mod_perl efficiency

Hello All,

I'm a newbie, and this may be a stupid question, but I haven't been able
to find clear help for this:

Building a CGI-based site with multiple distinct sections (and running
under mod_perl), is it more efficient to load one giant CGI script into
memory, or to create separate scripts for each section of the page (and
have each separate script load the same modules)? In the second case,
I'm not sure if mod_perl would be smart enough to load each "used"
module only once, or if it would be loaded once per call (or more
candidly, I assume it is, but I'd really hate to be wrong, so I'd like
to doublecheck to satisfy my paranoia :) ).

Thanks again!
