Assuming, you will be at Full Fibre area, whilst talking about 1 Gig package, and you mean in fact Full Fibre 900 package to be activated for you from BT:
Any such services are in principle CONTENDED and real performance will be really dependant on concrete environment and network as round yourself. But this is something, what you really know, isn’t it?
BT do not provide guaranteed speed in term, as your speed will be 900 Mbps/110 Mbps all the time, it’s almost impossible guarantee that.
What wifi will guarantee to yourself is connection between Exchange and your ONT/BT Super Hub 2.
This guarantee will be either 450 Mbps or 700 Mbps Download and 10 Mbps upload.
Yes, you read right, upload speed is absolute non guaranteed at all.
But before you start panic, my real world experience on my own FF900 is as I have most of the time 900+ Mbps (with occasional 1.1-1.2 Gbps) download and very stable 110-117 Mbps upload.
In very rare occasions, my download dropping down to 700+ Mbps and upload to 90+ Mbps.
To be fair, at previous building, which is only few meters away, I had much more fluctuation on speed end, whilst network was really on capacity on PON. But even like that, never dropped under 500 Mbps down and 90 Mbps up.
At a moment, PON, on which I am connected has a spare ports, and is not fully loaded, but less then 20 users. And even that results to some contended competition about bandwidth.
However, it’s not speed so much, what you looking for, and again, You probably know it.
My unloaded ping is in terms of 3 ms to 8 ms and loaded from 12 to 55 ms on Fast.com test.
On Speedtest by Ookla, all way down from NE to London 11.6 ms, and to Amsterdam about 15 ms.
Not tested game servers and respective pings, and jitters, but might imagine, as there will be similar results, due asymmetric nature of OpenReach / BT Fibre network.
Previously I had another provider at different area of city, with symmetrical 200/200 Mbps speed and ping 2-3 ms, but that’s something I can’t have here, whilst they do not cover private residential buildings. Even CF is not at our building on their own infrastructure, even less then 200 yards from us lying their optical network.
Unfortunately nature of leased lines, which OpenReach see as good money miner, means, as residential / SME customers will stay a long time on asymmetric network and with all that problems with that.
When talking about problems, you as gamer might had a little more expectations, then typical, even heavy user like myself, and find little problems quite big for yourself. Still, you have chance cancel contract in 14 days, then let’s see, how it will play for yourself.
