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.

the bt results for 76 mb service on both fttp and fttc seem pretty identical

Can you elaborate on that a little more?
By BT results do you mean the BT speed tester, or the BT Broadband Checker results?
If speed test, then...

I would expect FTTC @ 76Mb and FTTP @ 76Mb to both give similar speed tests.

The difference with FTTP is the is no "upto" on the sync speed. You get what you pay for.
If you already get max sync on FTTC (80Mb, about 76Mb on speed tests) then you wouldn't get any more from an 80Mb FTTP service.

what I mean by that is the sync speed on fttp should always be the 76mb whereas on the fttc 76mb service it could be significantly lower due to it being distance dependent so I would have thought the results for both services to be more different to what is shown in the results due to a percentage of users syncing lower on fttc

Just to add my FTTP (on 76/20Mbps package) speedtests so you can compare: http://www.speedtest.net/result/7108160696
https://www.thinkbroadband.com/speedtest/15201068192...

Must add speedtests were done on a UniFi WiFi system so expect some overheads compared to a LAN connection.

As other have said the speeds are subject to your SLA/package you are on, however with FTTP distance is not an issue whereas on FTTC only those near the cabinet on the upto 76Mbps service would see this speed.

What results though? What would you expect to be different? Your results?

Speed tests such as the one on this site are not sync rates tests but data rate tests and as has already been stated the actual data rate can be affected by many things other than the sync rate such as for example those testing their FTTP connections over Wi-Fi.

but wouldn't in theory the same %age of users on both fttp and fttc be affected by those things?so the sync speed should,with all things being even,be the one factor that differs the fttp service from the fttc service?

More people do get higher speeds on the BT FTTP services, but not enough to make massive differences to the figures.

On the PC theory - why would a person in rural Wales go out and by a much faster PC when upgrading from ADSL2+ to FTTP? That theory might stand for those willing to pay extra for FoD but not your usual person.

On FTTP the biggest factor for variations in the speed is the Wi-Fi element, or put this another way how many people reading this are connected to the router by an Ethernet cable?

Its late and had a long day doing coverage updates (so won't be uploading profile plots) but on the BT FTTP you get a nice 20% wide flat at the top end for Infinity 2, for FTTC this flat area does not exist really. In short compare the percentile figures in the table and you can see the difference.

Spped tests don't test sync rates but rather data rates and many users connecting by both FTTP and FTTC are using Wi-Fi so both technologies will be affected and such users often report lower speeds than their systems would reach if connected to the internet via a wired LAN. This brings down the median but there are almost certainly more FTTP users reporting at the top end of their speed range than those connecting via FTTC.

Identical Wi-Fi setups where the Wi-Fi speeds are well below the maximum rate for the connection are likely to cause users to report similar speeds regardless of the speeds their systems would be capable of reaching with a wired connection. The effect would be to drag some FTTP speeds down to similar rates to those reported by users connecting via FTTC. Not everyone running tests is using fast modern hardware and ac Wi-Fi.
