To bring an old thread back to life (I feel like a broken record)...
Pulling up threads was very slow this morning and even now. Earlier this morning I was lucky if I could even get a thread to come up at all (it would just halt after the FT header came up, and then never finish loading any thread - even when I was very careful to not move my mouse over the FT banner during loading). Now, it just takes longer than it should... on the order of 30-60 seconds per thread.
Hopefully these comments help nail the issue down further... I'm getting tired of posting them, and think many people have given up hope of a resolution.
