Re: What download speed should i expect?
Some RWIN tweaks may be required, particularly if using Windows default or tuned values for a lower speed.

The NTL CD, I believe, sets it ridiculously large, though in many cases, the value will be adaptive up to the maximum, starting at 1 packet size, and then doubling if the connection is dleay limited, but reducing if there is a high level of packet loss.

RWIN too low, causes slowdown as the connection ends up idling if it's got too much delay for the actual speed possible.

RWIN too high, can promote packet loss on poor paths, and can degrade responsiveness on multiple connections.
