Jie Yu commented on MESOS-2514:
-------------------------------
OK, so it still drop packets, but it has a better flow management and packet
scheduling algorithm so that a latency sensitive flow will less likely to be
affected by other high bandwidth flows. But I am still curious why you "no
longer see packet drops after this change"?

>
> When we enable bandwidth cap, htb is used on egress side inside containers,
> however, the default leaf qdisc for a htb class is still pfifo_fast, which is
> known to have buffer bloat. Change the default leaf qdisc to fq_codel too:
> `tc qd add dev eth0 parent 1:1 fq_codel`
> I can no longer see packet drops after this change.
