This test was taken on linux, about 20 feet and one room away from the
access point:


This was taken on the same box, about 10 feet and one room from the
access point.


In all cases, the uplink is a comcast box configured for 55Mbit down,
5Mbit up and just to make it weird this is a two router configuration,
where the nearest hop is over a powerline box (TP600) before hitting
the net.

I *like* that the test does not let you switch browser tabs (something
I do instinctively when something takes longer than 3 seconds.)

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.
