dbm choices - advice?

Hi all - I am looking at using a dbm-style cache system and was wondering if anyone has any recommendations from the plethora of systems listed here: http://us2.php.net/manual/en/ref.dba.php Is there a favorite? I know if probably depends on what I want to do, so in short, I am looking to create a temporary table that will be a composite of a ton of MySQL queries (hence the reason I am not just querying). I have thought about just creating a new database table to push my query results into, but I would love to make it faster if possible. Am I hopelessly misguided? I would love any feedback!
