Named vs unnamed prepared statement placeholder speed differencies?
Is there any speed differences when I use PDO's prepared statement with named placeholders (`:param`), compared to the prepared statement with unnamed placehoders (`?`)?

I am writing script which will do millions of inserts+updates, so any speed improvement would be welcome.
