[Bloat] How about a topical LWN article on demonstrating the real-world goodness of CAKE?

[Dave Taht]

Dear David:

I think freeswitch still has a public sip echo server which might be a
better test than skype?  I tend to think there is a lot of bloat on
the endpoints nowadays because it "helps" on not having to deal with
jitter
that the bloat on the rest of the internet induces. But 1sec you got
on skype in your test below is NUTS. I hacked a bit on BBB earlier
this year to get their number down to sanity.

I find endless videoconferencing nowadays to be really tiring and
frustrating. Am I alone in this? I have to go outside and scream after
two hours. Log off entirely after 4.

With a de-bloated router, lag was 40 milliseconds maximum, whether idle or loaded, and about 30 millisecond minimum, or a 3500 km round-trip, appropriate for the distances to the measurements points. By comparison, Rodger-Dogers was giving me lag times more appropriate for a test to Ankara, Turkey.

If you connect to it and say something, it will echo it back to you. If you tap on your microphone, it's fairly easy to get an idea of how much delay there is.
