I think using "speed" for "the inverse of delay" is pretty normal English, if
technically erroneous when speaking nerd or physicist.
Using it for volume? Arguably more like fraudulent...

Differences like speed and rate would go right over their heads.

The use of the term "speed" in communications used to be restricted to the speed of light (or
whatever propagation speed one happened to be dealing with. Everything else was a "rate". Maybe I'm
old-fashioned but I think talking about "speed tests" muddies the waters rather a lot.

Subject: Re: [Starlink] [Rpm] the grinch meets cloudflare's christmas present
Curious to why people keep calling capacity tests speed tests? A semi at
55 mph isn't faster than a porsche at 141 mph because its load volume is
larger.
Bob
HNY Dave and all the rest,
Great to see yet another capacity test add latency metrics to the
results. This one looks like a good start.
Results from my Windstream DOCSIS 3.1 line (3.1 on download only, up
is 3.0) Gigabit down / 35Mbps up provisioning. Using an IQrouter Pro
(an i5 x86) with Cake set for 710/31 as this ISP can’t deliver
reliable low-latency unless you shave a good bit off the targets. My
local loop is pretty congested.
Here’s the latest Cloudflare test:
And an Ookla test run just afterward:
They are definitely both in the ballpark and correspond to other tests
run from the router itself or my (wired) MacBook Pro.
Cheers,
Jonathan

Please try the new, the shiny, the really wonderful test here:
https://speed.cloudflare.com/<https://speed.cloudflare.com>
I would really appreciate some independent verification of
measurements using this tool. In my brief experiments it appears - as
all the commercial tools to date - to dramatically understate the
bufferbloat, on my LTE, (and my starlink terminal is out being
hacked^H^H^H^H^H^Hworked on, so I can't measure that)
My test of their test reports 223ms 5G latency under load , where
flent reports over 2seconds. See comparison attached.
My guess is that this otherwise lovely new tool, like too many,
doesn't run for long enough. Admittedly, most web objects (their
target market) are small, and so long as they remain small and not
heavily pipelined this test is a very good start... but I'm pretty
sure cloudflare is used for bigger uploads and downloads than that.
There's no way to change the test to run longer either.
I'd love to get some results from other networks (compared as usual to
flent), especially ones with cake on it. I'd love to know if they
measured more minimum rtts that can be obtained with fq_codel or cake,
correctly.
Love Always,
The Grinch
