This makes me wonder if I better keep using my own routines to get my parameters etc instead of using CPAN modules. Do these modules take their entire size as overhead or only the subroutines which get executed? I've also noticed a few weird things with a package I've made slurping more CPU (and memory) than it should take; I only use XML::Twig and XML::Simple in that package (for backwards compatibility for now)

Visual::XML::BEGIN is which I really wonder about ; only 3 calls and 17.5 time for executing these; while its merely a package of 3 routines made as proxy to be backwards compatible using XML::Twig with XML::Simple calls...
