speed test just published

I always thought that with fttp service you were guaranteed to receive the max (within a few MB) that that service was set as default for what you sign up for and wasn't distance dependent,so how does the speed results show it is as variable as fttc?what causes fttp to lose speed?

Factors such as Wi-Fi, congestion, shared nature of internet, slow computers

All FTTP does over FTTC is remove the distance variable.

That is correct ...

however speed tests look at throughput, and this can be affected by various other issues.

You are confusing connection speed, (sync), with throughput which depends on the factors others have pointed out.

On FTTP your connection speed should be as advertised. No "up to" applies.

You are only guaranteed to receive max line speeds (throughput) at all times on leased lines which I'm sure you know don't come cheap. Bandwidth on consumer grade FTTP lines is shared so its not unusual to see some kind of slowdown at peak times on FTTP lines. However BT/Openreach do specify minimum throughput to be expected on FTTP lines this was/is 40 Mbps but on the new BT Retail Ultrafast 1 and 2 services, this has been increased to 100 Mbps:

To be fair, I've noticed that the speed test isn't really giving an accurate picture at the moment - running an iperf test to ping.online.net single and multithreaded is giving far more consistent numbers than the TBB one.

Might want to ask your provider why it changed routing that appears to have put our testing services onto a poorer more congested link out of their network

I do realise those variables will affect the test results but would have thought most on fttp would have "fast pcs"(why bother with any form of fibre if tha pc is so old it limits your internet:-buy a new pc!)but shouldn't the base line that the tests operate on(the sync speed) be higher and as you say not affected by distance,the bt results for 76 mb service on both fttp and fttc seem pretty identical

Just because you have a good internet connection doesn't mean that you are going to get good speed results because you are still relying on the rest of the internet to also have good speeds.

For example: Let's say you have a 1gb intenet connection. The server you want to speed test from has a 100gb connection. At the very most that will only allow 100 people to max out the speed. In real life though, you might have thousands of people accessing a server and not always at full speed, therefore it's not normally noticable.

Like other have already said, your connection will be the speed you have paid for, however where ISP's group up loads of connections together you may see some speed decrease in the evening, try doing a speedtest the early hours of the morning like say 3am.

I have just done a speed test and I am currently getting about just under what I am paying for, so not bad for this time of the night.
