Hi everyone,
My name is Sam and I'm the co-founder and COO of Waveform.com. At
Waveform we provide equipment to help improve cell phone service, and
being in the industry we've always been interested in all aspects of
network connectivity. Bufferbloat for us has always been interesting,
and while there are a few tests out there we never found one that was
fantastic. So we thought we'd try and build one!
My colleague Arshan has built the test, which we based upon the
Cloudflare Speedtest template that was discussed earlier in the summer
in a previous thread.
We measure bufferbloat under two conditions: when downlink is saturated
and when uplink is saturated. The test involves three stages: Unloaded,
Downlink Saturated, and Uplink Saturated. In the first stage we simply
measure latency to a file hosted on a CDN. This is usually around 5ms
and could vary a bit based on the user's location. We use the webTiming
API to find the time-to-first-byte, and consider that as the latency. In
the second stage we run a download, while simultaneously measuring
latency. In the third stage we do the same but for upload. Both download
and upload usually take around 5 seconds. We show the median, first
quartile and the third quartile on distribution charts corresponding to
each stage to provide a visual representation of the latency variations.
For download and upload we have used Cloudflare's speedtest backend.
You can find the test here: https://www.waveform.com/apps/dev-arshan

We built testing it on Chrome, but it works on Firefox and mobile too.
On mobile results may be a little different, as the APIs aren't
available and so instead we implemented a more manual method, which can
be a little noisier.
This is a really early alpha, and so we are keen to get any and all
feedback you have :-). Things that we would particularly like feedback on:
* How does the bufferbloat measure compare to other tests you may have
run on the same connection (e.g. dslreports, fast.com <http://fast.com>)
* How the throughput results (download/upload/latency) look compared
to other tools
* Any feedback on the user interface of the test itself? We know that
before releasing more widely we will put more effort into explaining
bufferbloat than we have so far.
* Anything else you would like to give feedback on?
We have added a feature to share results via a URL, so please feel free
to share these if you have specific feedback.
Thanks!
Sam and Arshan

Looks pretty identical to what fast.com gave me. I'm on 50/50 fiber and
firefox 82.
