Re: 300+ms of hotel wifi bufferbloat - peaking at 1.5 sec!

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 "customers don't want upload speed".
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))
