If you want your Perl program to spend less time sending mail, you have to let someone else spend the time doing it. That's what's happening when you let sendmail figure it all out. It's not sending the mail in a millisecond. It's queueing the mail in that long, after which your Perl program gets control again. sendmail does more work on its own.
