First of all congratulations, glad to hear you got there in the end

If its any consolation, I also get lower than expected speedtest results on TBB:



Yet speedtest.net gives me the full 300 Mbps:

http://www.speedtest.net/result/7730724230

When I raised this with my ISP (Fluidone) they did real time NUT TCP testing on my line and they could easily see that I was getting the full 40 MB/s. That is the same i get when doing any kind of large downloads. I gave up a long time ago wondering why my speeds on the TBB tester don't quite match other speedtester results (probably something to do with the links from my ISP to TBB servers), however real life performance on my line suggests my line is performing to the max. Even the BT Wholesale tester is reporting max line speeds:

By all means report this to your ISP (if possible get them to do nut tcp testing) but I would also do some independent tests, eg download test files from here.

Btw probably the most reliable speedtester I've come across is AAISP's, even for non-AAISP customers:

I can break the 300mbps barrier on other speed tests such as dsl reports which has 12 threads. I'm not sure what the normal pattern is for FTTP but the speed builds very gradually and only maxes out at the very end of the speed test.

Your latency of 37ms seems very high for FTTP - and higher latency does cause TCP to ramp up more slowly.

Are you on a direct wired connection to your router when running these tests?

Can you check the port status to see if the NICs are auto-negotiating to 1Gbps - both between PC and router, and between router and ONT? (if your router will show this)

Are you running Windows? Try booting your machine from a Ubuntu Live USB and doing the test with that. I've seen laptops which max out at 150Mbps when running Windows but can fill a full 1Gbps when running Linux.

Alternatively, if you know someone who has a Mac laptop with a gigabit ethernet adapter, ask them to come round and do a wired speedtest.

It depends on where they are, they might be far from London, or the TBB Servers.

I am about 8 or so miles from the London eye and I get the following:



But it says my latency is 21ms yet my BQM says its about 2 to 3 ms between me and TBB server, same when I ping google.com is 4ms and the bbc.co.uk is 2 to 3 ms.

I also get a latency of about 12ms from our dedicated rack server located in France, so not sure what is going on with the latency on the TBB Speed test, I think there has been posts about that topic.

Which matches my BQM, so yeah a strange thing LOL

I am also not that far from Telehouse so that might help as well

I thought I would give it a go and I got the following from it:

[Download]
315.06 Mbit/s

[Upload]
56.38 Mbit/s

[Ping]
8.57 ms

[Jitter]
2.62 ms

So its nice to have different places to do test so that we can compare results.

I am very glad you have finally got it all installed and its working.

Ran a few more tests. To be honest I ran a few earlier and couldn't remember what configuration I had. So the following tests have been carried out on my Macbook Pro directly connected to the ONT with a gigabit adapter and a direct PPPoE connection. So nothing else using the connection. Single thread speed on the site tester is still very low...



Like before I can get higher on the multi threaded speed tests but still not really getting max performance

DSL Reports

Ookla

I also tried some large file downloads as suggested. Tried the 1GB one from this site which peaked at 11.5 MB/sec but mostly sat about 9MB/sec so average 72mpbs with a peak aronnd 92mbps.

Like I said I'm very new to FTTP and maybe expecting too much but for what it's costing me I would prefer to get all I can from the connection.

I wonder if there is a possible single stream cap of 80Mbps or 100Mbps on Zen's service between NI and the mainland. Giving the effect of what would be congestion if present within the mainland.

I do recall getting 92Mbits at one point on our connection, but that was when the LAN Port was stuck in 100Mbit speed, I just rebooted everything, ONT + Router and all our switches here and all was good again.

Have you tried doing the tests the early hours like 3 to 5 am.

I like the URL you get redirected to if you try http://speedtest.aa.net.uk/ instead!!

Up early this morning so ran a speed test about 7am. Getting better speeds on the TBB speed test but single thread still poor. I also thought the multi thread should be closer to the max of the connection. Definitely running at gigibit speed on the ethernet port.



Ran the other 2 speed tests again and got about the same, maybe a wee bit quicker on speedtest.net but notthing significant.
