I'm not convinced throwing money at it will do it. A while back I got the impression the administrators were keenly monitoring the situation with a view to working out the problem. However my recent reports have gone largely ignored. (With all due respect to the forum admins who are no doubt very busy).
I think, though, that some of the "helpful" features, like notifying you of new posts might be bogging down the database. Through no fault of my own, when I check my "subscribed" list there are dozens of pages. That's because every time I reply I get auto-subscribed to that thread. So I wonder if hundreds of people, being checked for thousands of threads, might not be slowing it down.
BTW - another massive lag spike around the time of this post.
