Hi William, Thanks! It is a good point. Do you know by chance what would be the packet size average by direction: 1) to subscriber; 2) from subscriber? Eduard

Wrong math. The internet average packet size is very close to 750B - it has been published many times in many places.
Of course it is. 1500 byte packet one way, 46 byte TCP ack packet back the other. Averages to, guess what?
After the synack, the ack packet _length_ doesn't contribute to the latency and doesn't contribute to the throughput at all.
