Switched to Infinity 2 this morning


[link to this post]
 
engineer says it's sync'd up at 80 / 20

The BTO engineer was done by 9am

Predicted (by the online checker) was 65.3 down and 20 up

[IMG]http://www.speedtest.net/result/1929586172.png[/IMG]
74 down 16 up

The tester on here (TBB) shows results that are lower than expected.
(hence not posted the result)


just need to change my sig on here now.

Oooh, nice ping, too.

Enjoy it! smile

That sorts out the question raised in http://forums.thinkbroadband.com/bt/t/4119412-infini...

A customer will get the max the sync speed will allow and it will NOT be restricted by the checker predictions..

He was predicted 20 upstream and is getting 16. Doesn't really disprove anything.

It told me 20Mb up but ended up with 15Mb then after several days it picked up to 18Mb and has been stable ever since.

PS
No matter what I do or try I can't seem to change my sign, any idea's as to why?

Astrology is based on your date of birth, which is fairly constant.

Remember that the observed throughput will always be lower than the sync rate.

On ADSL IIRC the maximum expected throughput was about 85% of sync rate. I'm told the expected maximum throughput on FTTC is more like 92%, though my results seem to agree with the 85: When I was on 40/10 the best speedtest results where 8.5mbit upstream IIRC (as far as I know I was syncing at the full 10 but I've not unlocked the modem to find out for sure), I've just moved to 80/20 and I'm now seeing 16.5 as the best result upstream though I've not done much testing yet.

And to think that I remember when you had to pay a hefty price to push any part of your local wired network faster than 10mbit/s...

Current ISP: Andrews & Arnold (AAISP) via FTTC at ~40Mbit down (has occasionally dropped to ~36) & ~10Mbit up, joined July 2011.
Previous setup: Be Pro with UploadPlus (ADSL2+, AnnexM), 12ish Mbit down, 1.6 up, happy customer for ~2.5 years.

My experience is that "observed" downstream speeds will be 97% of your sync thanks to the IP profile, and user-data throughput (i.e. your average HTTP speedtest result) will be about 94% of your sync thanks to an additional 2-3% of TCP overheads.

On the upstream however observed speeds are closer to 97% because there is no IP profile (in practice) - but most speed testers generally fail at testing fast upstream speeds.

Speedtest.net for example, usually comes up with 16.5mbps on mine line, TBB's speedtest shows only 6mbps, but Visualware's UDP test shows 18.5mbps. However a single FTP upload to my own server proceeds at 19.4mbps.

In any case the quick investigation of Speedtest.net's results shows bursty transmission and my line sitting idle for a third of the test, and a result that was considerably higher than the actual speed of data sent on the line during the test.

Basically, most speedtests are especially [censored] at uploads.

Please do, it might help the guys at TBB work out why the TBB tester is so flaky with BT Infinity2 connections.
Here's mine (which is, BTW, the best result I've had from the TBB tester in weeks).
My Broadband Speed Test

Here's my Speedtest.net result (for comparison).

It is worth pointing out if you try several of the Speedtest.net servers, you'll find a few in the UK which give similar results to the TBB tester.
I doubt if some Speedtest.net servers use multiple thread tests, while others use single thread tests (which has been touted as one possible explanation why the TBB test results are so much lower) so it points to some other problem (maybe some servers are being overloaded - possibly one being the TBB test server or BT have some routing issues).

If I try a Speedtest.net with two Xilo servers (one in Manchester, the other in Maidenhead) I get vastly different results (around 75Mbps/16Mbps and a ping of 10ms for the Manchester server, and around 28Mbps/12Mbps and a ping of 26ms for the Maidenhead server).
I'd find it hard to believe one Xilo server is applying the test in a vastly different way from another Xilo server, so it has to be to do with BT (throttling???), routing, or server congestion.
This makes no sense to me (unless BT are applying some far out routing) as I'm 44 miles from Maidenhead and 107 miles from Manchester (direct "as the crow flies" distances), so God knows where BT are routing my connection (if the ping to do a 214 mile round trip is 2.6 times lower than the ping to do an 88 mile round trip).
