I don't think you're likely to see any measurable difference, not until your sessions get VERY big (I'm guessing megabytes). There's is overhead associated with both forms - the SESSION data must be serialized/de-serialized, the mysql calls organises data to/from an associative array etc., but what is hauled out of the database is essentially the same, it's only the transmission method that differs. /Per Jessen, Zürich -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
