Subject: [Bloat] goresponsiveness learned a few tricks...

Just a quick shoutout to Will Hawkins goresponsiveness effort
(h++ps://github.com/network-quality/goresponsiveness: open source go
implementation along the lines of the RPM IETF responsiveness draft
(h++ps://github.com/network-quality/draft-ietf-ippm-responsiveness).
The goal I think is a quick latency under working conditions/latency
under load for the rest of us. I think the draft likely will get a
last call soon, so whoever wants to add something to the spec or just
wants to comment, now would be a good time:
goresponsiveness is currently acquiring a few nice features, like the
ability to compare the latency between idle and working conditions,
run both saturating loads concurrently, and to report the sub results
for the "self" probes (measuring latency within the load generating
connection/flow) and the "foreign" probes (measuring latency outside
of the load generating flows)

The beauty of the self and foreign reports is that here we can see
that my cake'd upstream does a decent job to preserve foreign
responsiveness while in the self responsiveness we see how TCP
self-congests like there is no tomorrow... Please ignore the download
direction, this is over a 100 Mbps USB ethernet dongle and my true
download shaper is set to 105 Mbps, so this is mostly the bad USB
dongle in action...
