This is not a solution by itself. Wendell may have a smoother running forum after deleting a number of archived postings from the database table. But what's with a forum with the (former) number of around 235,000 active postings?

I agree, as I will reach that number again soon, and will likely experience more slowdowns. It does seem to get slower and slower as it grows and I keep throwing things at it to help performance. Probably the most helpful solution so far has been the ZBBlock addition. Optimizing the database each night helps a lot, too.
