While I agree that upload speeds aren't great, it doesn't mean that the
buffers aren't big. Buffer sizes of the order of MB's are uncalled for
at the edge, unless we're talking really high speeds. The miniscule
performance increase for single TCP flows doesn't really justify the
potential increase in latency for everyone else.

There's a corollary of the bufferbloat phenomenon: buffer drain time. It's not the size
of the buffer, but how long it takes to empty. And US ISPs continue to say

If the ISP upload speed was symmetric you'd likely never notice the 1-2MB of
buffers.
I guess what I'm getting at is why do you continue to say buffers are too big
instead of saying ISP upload is too slow?

I would get a kick out of it if folk here tried this new speedtest
periodically (on the "cable" setting) during the nanog conference. ;)
There is a hires option for more detail on the resulting charts...
(or fiddled with "flent" (flent.org))
