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?

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.
