One can use the BB cnt as analogous for messages per unit time. It by default turns on TCP_QUICKACK so one can compare the TCP RTT vs the app level bounceback (-i is recommended for tcpinfo sampling.) There is an option to add a full duplex TCP stream to the same dest along with the bounceback traffic. If you use --trip-times you'll get a histogram (BB8) of the one way delays too (clocks must be sync'ed and assumed so) This is designed to be a simple socket level test.
