I have always disagreed with the "don't reduce segment size" crowd,
btw. If you have a rate where you need to go below 2mss, it doesn't
hurt the network to reduce the size of the packet, and you can keep
the signal strength up by reducing that size and continuing to sample
rtt, to respond quickly.
Even if you are only passing a single byte of data, by lowering this
below everyone else's 2mss noise floor, you still eventually win, and
also you occupy space in packet fifos, reducing overall latency, as
bytes=time. IMHO.
this ignores per-packet overhead (which is headers + inter-packet time). As data
rates get faster, the inter-packet time is not shrinking to match.
This is especially true in wifi where the headers are transmitted at a much
slower speed than the data for compatibility reasons (as there may be many
different data rates on any channel), but it still applies to wired networks.
