Performance Problem [solved]

PHP usually calls session_write_close() automatically after code execution (and I was used to that happening), I read on the forum someone asked if it was okay to place it in __destruct() and the response was no and I didn't understand their reasoning, sorry I don't remember where I read that.

__destruct() will rarely be called when you need it, and is kind of unpredictable at times.

If I want to simulate PHP's call on script completion where would I place session_write_close() or is there a way to turn that automation back on?

Is that this variable? $config['sess_regenerate_destroy'] = FALSE;

No, sess_regenerate_destroy has nothing to do with it and it's already automated - PHP will close the session itself. Point of calling session_write_close() yourself is that you know it will be beneficial to do it at a certain execution point, there's no way to automate that.

Thank you for the clarification.
