Right, I knew there was something wrong somewhere :-) > 4000 km one way == 8000 km two way, 8000 / 168300 = 47ms in my book, > theoretial optimum. > > With an RTT of 47ms, you can move 16k per RTT, or or about 340k/sec. It's where I don't quite agree: for a bulk transfer, there is no RTT to account for, you only need to take into account the one-way delay, TCP does the rest for you assuming the window is large enough.
