Here are 3 consecutive runs. U.S. (New England). 75Mb/sec FTTP
Although the relative times are interesting, I don't trust the
openspeedtest.com result.
I ran its standard browser-based test several times. It reported
download speeds of ~50 Mb/sec,
and upload speeds of 4 Mb/sec (twice), 2.8Mb/sec (once) & 49Mb/sec
(once). Other
sites, including speedtest.net report 75 Mb/sec (up and down)
consistently. I picked servers
in the same geography as the one openspeedtest used.
The FAQ, About us, & Contact us links on their web page all result in 404s.
One possibility is that my IPv6 connection is via a (HE) tunnel - your
test doesn't indicate the
peer IP address that it uses. If it's using IPv6, I would expect lower
speeds - but not that low.
openspeedtest.com does report both A and AAAA records.
In any case, how you interpret the data is up to you.
Note: I excluded a previous run because automatic anti-virus scan
increased times.
It's always a good idea to run benchmarks several times and discard
outliers.
