This was a test taken *during* a 2 minute rrul_be test.


Flient (formerly netperf-wrapper) data here:

Puzzle over this!
http://snapon.lab.bufferbloat.net/~d/lorna-wifi/reconcile_this.png and
the rawer data.... in comparison to this and other of these new
speedtest reports.

There are a couple other tests of the same link in the  same
configuration (laptop on lap 10 feet from the access point through a
wall) [1] in the same dir testing upload and download (without
simultaneously running the new dslreport tests)

CDF plots are nice. So are mountain plots.

>> Folks,
>> I am delighted to pass along the news that Justin has added latency measurements into the Speed Test at DSLReports.com.
>> Go to: https://www.dslreports.com/speedtest and click the button for your Internet link. This controls the number of simultaneous connections that get established between your browser and the speedtest server. After you run the test, click the green "Results + Share" button to see detailed info. For the moment, you need to be logged in to see the latency results. There's a "register" link on each page.
>> The speed test measures latency using websocket pings: Justin says that a zero-latency link can give 1000 Hz - faster than a full HTTP ping. I just ran a test and got 48 msec latency from DSLReports, while ping gstatic.com gave 38-40 msec, so they're pretty fast.
>> You can leave feedback on this page - http://www.dslreports.com/forum/r29910594-FYI-for-general-feedback-on-the-new-speedtest - or wait 'til Justin creates a new Bufferbloat topic on the forums.
>> Enjoy!
