Note the huge amount of time taken in 'Main:Begin'. What does that mean? Does that mean that the majority of this code is burning its time in the actual main function...
Here's what it means 

D:\>
D:\>more hi.pl
BEGIN {
   use DBI;
   use CGI;
}

hi();

sub hi{
    print "Hi there\n";
}


D:\>perl -d:DProf hi.pl
Hi there

D:\>dprofpp tmon.out

Notice how hi has very short runtime, while loading DBI/CGI takes more time.
