I've checked through the code but I can't seem to find a means to leverage [oci_set_prefetch](https://www.php.net/manual/en/function.oci-set-prefetch.php) in order to optimize performance for certain queries. May be more of an enhancement...

There appears to be some performance issues with this libary when attempting to store large arrays. So far I've profiled it to having spend lots of time in the preg_match...
