We would have to see his script as there are several variables at hand here.
1. Is he using do or execute with his perl-sql? If he is using execute
then he is getting the advantage of prepared query inserts.
2. Did he use a single transaction? If so then he is not paying for 2
million commits, which he would be with the procedure.
