In fact I have in fact two questions in one...

1) I am in the process of writing a CGI script that would be run quite often, and would need only a few of the many possibilities provided by CGI.pm (mostly param and header)... And I heard that using CGI.pm can quite slow down a script... Would use CGI /:cgi/ help, or should I rewrite the few bits I need?

2) This script will have some very different behaviors depending on the parameter the user feeds to it... Since it's CGI (no mod_perl yet), would something like 

if($do eq 'this') { require This } else { require That }

help? It should be quicker than to parse and reparse all the (mostly useless) subs every time, shouldn't it?

Thanks for your comments.
