This is influenced mainly by the = flow-isolation and priority-queue mechanisms, not by AQM. Where AQM = helps is the effect of a flow on its *own* latency. Ok, so this might explain why I haven=E2=80=99t seen large latency = differences between sfq and fq_codel or Cake in the RRUL test.

And where can I find the latest tc?=
