There would be overhead, but how do the cgi-bin/<scriptname>.pl programs communicate with the DB? That has all the same overhead, plus the database's authentication.

If the individual programs typically run a small number of queries per invocation then the overhead of DB authentication is relatively more significant.

Also, if the website is heavily used the DB might be "happier" with a small number of connections making many queries vs many connections making few queries each.
