I7 with 16Gb Ram. I tried it with the AV disabled and it made no difference. When other people do this they either get the same or faster speeds not significantly less which is what I do not understand.

Fast.com tends to over read, based on looking at network card throughput and figures displayed.

This is BT900 over wireless https://www.thinkbroadband.com/speedtest/16009896835...
Would switch on the PC but its late, an old one is http://tbb.st/1598039865460825655

Posting the link to the results from the Thinkbroadband test can sometimes give some clues to issues.

Connection is via Thunderbolt to a Belkin TB2 dock, and gigabit wired ethernet from there. Using iperf3 to a local server I can max out the gigabit easily.

The browser I use is Chrome. Firefox is slightly worse - it gives 230-250M.

I suspect the bottleneck is because of the external 4K monitor I use, connected via the same thunderbolt dock to DisplayPort. During the test, the top CPU processes are "Google Chrome Helper" and "Google Chrome Renderer".

SSD is encrypted, but a speedtest website isn't going to be writing all its downloads to disk (or shouldn't be)

Anyway, I was just making the point that the bottleneck is often the client machine, especially if using a browser-based speed test.

It is an interesting finding, given MrSaffron has shown faster than gigabit working on the TBB tester in a browser. There does appear to be quite dramatic performance differences for browsers on different Operating Systems, which is very interesting.

Nothing special and was literally first speed test I've ran today

Thanks.

Try running the thinkbroadband test and posting the results. this will tell people more to judge what is going on. If you post both, Mr Saffron will be able to see more of what the potential difference is.

Yes indeed I am using a Mac.

I just got my service the other day, very happy indeed but I was wondering also on the speed difference & using a 16'' mac with Belkin usb-c Ethernet.

Ok, I will post them tomorrow, one though the Hub and one connected to the ONT.
As my original post, I am not trying to see why I cannot get 900 - that will come later- but why the same speedtests are slower with a direct connect than through the hub when the perceived wisdom is that this is the way to go to see whether the hub is the problem or the fibre/ont.
