On CHBRPW we have the same problems, and what we have done and are doing is archiving comments by copying them onto forums and then deleting them after. That way, they are saved and stored, and there is no lag on comments pages.

As for pointless comments, that would occur on talk pages as well. And if a comment is really out of hand, an admin is able to delete that.
