sch_fq depends on ktime_get(), so it is a no go if you have clocksource using hpet. pfifo_fast doesn't have such issues. Another issue is TCP CUBIC Hystart 'ACK TRAIN' detection that triggers early, since goal of TSO autosizing + FQ/pacing is to get ACK clocking every ms. By design, it tends to get ACK trains, way before the cwnd might reach BDP. _______________________________________________ Bloat mailing list [email protected] https://lists.bufferbloat.net/listinfo/bloat
