Well, like I said, there is a 1 connection per transfer limit that
times out every 5 seconds. What usually seems to be happening is that
I am connecting to people that are busy, because you see the transfer
rate jump up then down just for a sec ... That's what that is.

Also, if there are any P2P sources, shit will start transferring
right away. And the more P2P sources, the faster it will go.
