For us this is the biggest one.
I will have customer call, speedtest says 384K. Look at the radio and
we are pushing 2.04M in on a 2M connection. "Ask your kids to turn off
all their devices and try again." "Oh, wow, I am getting the full 2M
now. What did you change?" Then the long explanation about shared
bandwidth on their connection.
Has to be the same for businesses, though it is kind of hard to have all
the other kids turn off their computers.

We have found that the tests are "fairly" accurate (well speedtest.net
anyhow), *_BUT_* only in controlled environments. Your end user is

look I am right it is slow, xyz speed test says so! What he does not
realize is that Johnny intern in the warehouse has set his computer up
to grab torrents for him while he picks stock and then just dumps the
off to flash before heading out. Ok, that is just one example, but
all sorts of other traffic can come into play.
We tell our customers that we are not at all interested in speed tests
unless we have a support person on the line watching their link for
other types of traffic as well during the test. We also host their
speedtest.net mini (free) on own of our own servers so that we can
eliminate any Internet oddness causing problems with the results. The
mini however only seems accurate up to about 25-30 Mbps in our
experience at which point the results are only ballpark at best. Ookla
claims mini is good until about 50 Mbps, but that has not been our
experience.
Just what we have experienced with speedtest results.

*Subject:* [WISPA] Internet Speed test..are they inaccurate with wireless?
We mostly deal with business customer and guarantee bandwidth to
customers. We validate the bandwidth using IPERF from a Linux server
off of our BGP edge routers down to the customer and IPERF always
shows the customer getting the bandwidth they signed up for. We use
QoS to control bandwidth and make sure to not oversubscribe any one
link....small ratios of 3:1.
Of course eventually at some point the customer runs one of those
stupid bandwidth test on the Internet and the results are woefully
inaccurate (not in our favor)...but of course customers take the
results as gospel. AAARRRRGGGGHHHH!
It's not our internet connections, we have three 100Mbps BGP links and
none of them run at more then 50% during peak loads.
Has anyone else found those Internet speed test to be woefully
inaccurate? Or is something else going on that I'm missing?
Thanks,
Bret
