that's a BIG difference.
% perlbloat 'require CGI'
require CGI added 784k
% perlbloat 'require CGI; CGI->compile(":all")'
require CGI; CGI->compile(":all") added 2.0M
try without preloading CGI.pm/CGI->compile in either.
p.s. this is the perlbloat script:
use GTop ();
my $gtop = GTop->new;
my $before = $gtop->proc_mem($$)->size;
for (@ARGV) {
if (eval "require $_") {
eval {
$_->import;
};
}
else {
eval $_;
die $@ if $@;
}
}
my $after = $gtop->proc_mem($$)->size;
printf "@ARGV added %s\n", GTop::size_string($after - $before);

Won't someone comment on this post? That's a chunk of memory!
