Please do not use speedtest.net as a benchmark. They're indicative and not at all consistent or scientific. I have to occassional deal with techno cripples who insist their 100 Mbit/s is not getting full speed.
You have to remember a lot of the Ookla affiliated speed test servers are voluntary, and do not necessarily have oodles large backhaul links to support multiple people testing at the same time, so it's really a lottery if you hit the server at the right time and get "appropriate" results....

Yes, in theory if you're plugged in directly to a DSLAM port on the DSLAM itself before you hit the IDF frames in the exchange. Real world, if you live across the road from the exchange, 20 Mbit/s.
Also depends on your wire guage and a heap of stuff....
Ofey, post up your full stats, attainable line rate, noise margin and I'll have a look. Also are you naked or LSS?
here are my stats...
*puts geek hat on*
I like to know what's going on...
my SNR
My noise margin - yes I have some interference on a frequency, possibly an FM radio station?!
number of bits I can squeeze per tone/carrier frequency.
