Subject: Re: [Codel] fq_codel_drop vs a udp flood

Message-ID: <CAA93jw4JrsR+3pR31OvghppU6n3VnvFodnFNfLkj8=4K_u4YNw@mail.gmail.com> (raw)

Thus far this batch drop patch is testing out beautifully. Under a
900Mbit flood going into 100Mbit on the pcengines apu2, cpu usage for
ksoftirqd now doesn't crack 10%, where before (under
pie,pfifo,fq_codel,cake & the prior fq_codel) it went to 88% and
ultimately bad things happened, like losing routability.
I've had it running for hours and I hardly notice it's there.
Performance for the normal cc controlled and/or sparse flows is
unaffected, aside from the uncontrolled flows eating their percentage
of the link.
Nice work. Thx. This should go into -stable.

Sigh. The RFC is past last call...
