Jie Yu commented on MESOS-2514:
-------------------------------
Just to understand the problem. Are you saying that pfifo_fast have buffer
bloat problem because it's buffer size is small? Or there are some other
reasons?
> Change the default leaf qdisc to fq_codel inside containers

>
> 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.
