Serious question as I know nothing of all this.
Is there a point when the "big numbers" become irrelevant?
I'm running about 2.8Mb/s & 0.8Mb/s
That does everything I need.
I never download movies, my son plays on line games with no issues.
The Wifi is fine in the back garden.
TP pages open as fast as I click them, unless someone has abused the system
and is posting multiple files at around 5Mbs ea.
(but of course I have the technology to correct that.

)
As a side note we were promised Fibre optic years ago,
living in a developing city, with many "centres of excellence"
Some area's now have it, but its not here.
BT say that it is, until you quiz them.
All they are trying to do is "cold call"
get you to sign up to their unlimited package at a very cheap rate.
Then Slap you with a large increase, once Fibre is actually available

I don't think so
