I am glad the codel patches for mahimahi resurfaced. I hope they fixed
the infinite queue length problem that codebase had.
I wish every uni had a CS244 class.

My favourite part of that is "disabling TSO leads to a doubling in
throughput". In precisely the sort of situation that TSO was intended to
help throughput.

Again, my take on it.
Mimo is using multipath to enhance signal and date rate. Basically multiple
antennas for tx and rx to leverage multipath propogation. But its always
between one ap and one client at the time, standard wifi stuff.
Mu-mimo is the same mimo effect, but it can talk to multiple cl
Why would disabling TSO would have such a large impact when he also states
that there is 32MB of buffer?

Firstly, these algorithms use drop and ECN in addition to delay to trigger
congestion avoidance behaviors. Having said that.. Yup - using delay as a
trigger for a host-based congestion control algorithm has merit when delay has
an unambiguous correspondence to congestion. In a tail-drop worl

Is the 1900AC MU-Mimo? If not then its still normal Airtime limitations,
unless you consider concurrent 2x2 2.4GHz and 3x3 5GHz as a MU setup.
Also there are very few devices with builtin 3x3 ac client. From the top
of my head I can not think of one.

Folks,
I mentioned that this fellow could try OpenWrt to turn on SQM/fq_codel, and it
worked as well as we all hoped/expected... See:

Nice Job to all who contributed to this. (In case no one has said anything nice
to you today :-)

good to see this patch go by last week.

there is a writeup in lwn.net but it won't be public for another week,
if you are not a subscriber.
