1) In the 7 MB/s range. Unchanged from before. If it was load related, when the 2 dropped, I would expect the surfing members to be overwhelmed. They are not. They handle the additional load fine, up to 15 MB/s sometimes.

3) No. That would be nice! At least I'd have somewhere to start.
2 pieces of curious info: The 2 usually block together. Rarely does one start blocking without the other. And when they are blocked they take an abnormally long time to restart. While waiting for the restart to happen, with the "..." crawling across the screen, server load drops to 0. Vs while running but blocked, load is at ~ 1. And while running normally, load is ~ 10.
