At some point, with increasing bandwidth and increasing RTT, you end up with your effective bandwidth capped by receive windows and/or send buffers. Cross country high def video might not be quite enough to hit that, but intercontinental high def video would be.
Being closer means faster initial 'slow start', but also faster 'slow start' on congestion, which is why you get a bigger share.
sure. but thats really just a window being under the bandwidth delay product. the discussion makes it seem like you suffer an outright linear performance hit
