Yeah, I would be interested in this too. Is CGI.pm being used from within a test script, or from startup.pl/httpd.conf? You could also try only importing things like use CGI qw/:standard/. I believe CGI.pm has some magic code inside to help with memory when you do so, although I haven't perused the source in quite some time now. Either way, if CGI.pm is being preloaded I wouldn't think you would see as much of a hit, since it stays resident in memory and isn't loaded each time the script is called.

Cheers,
