I see your point, me living in Sweden may explain why i never had internet speed problem. Here, almost everyone gets 10mbit if not 100mbit. (And it actually is 10mbit)
But still, with bad infrastructure, you will not gain any more speed with 1tb internet connection either. Im guessing your provider tells you that they are providing 10mbit connection to you, which is a lie according to what you explained, right?
You living in sweden is why you've never complained.
BT is outright shocking (probably infinite is ok, however this is in response to Virgin deploying fiber- and they're directly competing- thus! in area's with fiber coverage you get a choice of BT or Virgin, in the other areas.. well, sucks to be you!)
I get, on average 150KB/s with around 1s latency at all times (when it goes lower than 1s I celebrate)[0].
I live in the tech part of london, seriously confused as to how this is acceptable, but a leased line to bring me up to your speeds would cost me more than I earn in a month (I checked).
I spent some time working for a company that made switches that would do that (Guaranteed minimum, but the sum of the maximum allowed speeds could exceed the link speed). There was no interest from anyone who sold to consumers, but business ISPs liked it.
The perception in residential is that customers don't understand what they want and can't go somewhere else, so you slap the biggest speed number on it that won't get you sued and then provide them crap service.
For most of us the internet speed is the biggest problem. My home internet speed has some very big issued on peak hours.
It's not unusual for the connection to be unusable for an hour.
Luckily peak time is usually when everybody is home from work and i don't really need to use it at that time.
