If this is indeed the case, it would be interesting to see what happens w= hen the option is disabled at the server, so that the transmission of a new= chunk can start at a generally faster rate. 4K video makes this option eve= n more relevant, especially when RTT is large. With tcp_slow_start_after_idle disabled, the fq_nocodel scheme of Toke's st= udy (http://dx.doi.org/10.1016/j.comnet.2015.07.014) would also be good to = evaluate, especially with a total buffer size much larger than BDP: DASH do= es not suffer from self-inflicted delay as much as it does from packet loss= es, and empties its dedicated queue in between video chunks.
