A key point of this video is to illustrate capacity with large vehicles, = that move much content, but themselves do not have =E2=80=98quick=E2=80=99= transit, or round-trip times. That correlates nicely with the metrics = for RTT and CWND in speedtests. Examples focusing on =E2=80=99top-speed=E2=80=99 of vehicles is missing = a bit of the point that Internet =E2=80=99speed=E2=80=99 metric is truly = more about capacity rather than responsiveness. I=E2=80=99ll be = re-thinking the use of those.
