Hey, bud. We have a few threads on this so im going to merge this one to an earlier thread that has some information in it. There has been quite a bit of testing done by folks on the forums, hope you find it useful.
EDIT: @James35 I forgot to mention, it goes by PDO now, we called it something else early on but i forgot what that was. So run you a search on PDO and you will find some great information on it.
