NTL Speeds and Throttling

[fatlip180]

Just how accurate is the speed test at the top nav bar????

I am on a supposedly 10 meg line

I ask because on adslguide i get 1.5 mbps

Ive run spyware check etc etc, reset my modem and that the best i get. On bandwidth place i get 3 meg max.

However on the test above on the nav bar i get:

1st 512K took 422 ms = 1213.3 KB/sec, approx 9998 Kbps, 9.76 Mbps
2nd 512K took 437 ms = 1171.6 KB/sec, approx 9654 Kbps, 9.43 Mbps
3rd 512K took 438 ms = 1169 KB/sec, approx 9633 Kbps, 9.41 Mbps
4th 512K took 437 ms = 1171.6 KB/sec, approx 9654 Kbps, 9.43 Mbps

Overall Average Speed = approx 9735 Kbps, 9.51 Mbps

My upload speed is always around 500k btw on any test i do.

you are quite close to your 10mb witht ose try my 2mb speed.

1st 512K took 2844 ms = 180 KB/sec, approx 1483 Kbps, 1.45 Mbps
2nd 512K took 3249 ms = 157.6 KB/sec, approx 1299 Kbps, 1.27 Mbps
3rd 512K took 4547 ms = 112.6 KB/sec, approx 928 Kbps, 0.91 Mbps
4th 512K took 4891 ms = 104.7 KB/sec, approx 863 Kbps, 0.84 Mbps

Overall Average Speed = approx 1143 Kbps, 1.12 Mbps

It can go lower before the night is out.

ADSLGuide's tester is a bit congested at the moment, as is ntl's external connectivity.

Try the Telewest one than. http://tenmeg.pwp.blueyonder.co.uk/

Thats a good link, some solid tips on there, nice

An update here.

I have noticed some weird goigns on over the past week or so, peak time performance up etc.

What seems to be going on is it slows down as normal late afternoon and between 5pm and 6pm its very bad, lag spikes in ssh, slow speeds etc. Then at 6pm speeds shoot up (download on ftp went from 70kB/sec to 820kB/sec) and the lag in ssh dissapears, browsing is also more responsive.

So I have a theory shaping is on here it fits in with the 6-12pm times been mentioned as well. If it is shaping ntl appear to have made a good job of it, what I use my connection for benefits from it.

any evidence to back this up

Odd thing to say. The guy gave the observations that lead to his speculation in the above post, which I thought was quite clear. His post states what he saw, then he offers a potential explanation.

He is giving his opinion, as is his right, nothing more.

You seem a bit touchy about the prospect of traffic shaping being active and customers knowing about it. Let's face it had to happen sooner or later, those Allot NetEnforcer AC-1000 series boxes had to get exercise eventually.

Indeed

The fact is they are there, Turned on, And warming up. NTL will not have spent all that money on buying them, then having them installed, Without the intention of using them. My feeling now are if they are only used between 6.00pm and 11.00pm then no harm done. I am also under the impression that its only p2p upload that is affected.

[Chrysalis]

if its only upload and they are on here then that would indicate it was upload saturation which confuses me since I can always max my upstream any time of the day and ntl are increasing upstream allowance on the middle tier, I was also told by a few different people upstream utilisation was normal and not overutilised. But it happened again tonight, 6pm big speed boost latency dropped.

evidence from within ntl? to say its on now no, and if yes I wouldnt be able to disclose anyway.

But like the other 2 guys have said the hardware is in place.

I only have evidence of my own experiences and the pattern doesnt fit in with what I would expect to happen on a unshaped connection.

The speed test here is giving mixed results today, between 5MB - 8MB however when I download from a newsgroup I'm getting full speed

[Chrysalis]

its stopped now speed remaining slow in the evening again.

NTL 2MB

Mon, 1 May 2006 19:38:13 UTC

1st 512K took 13250 ms = 38.6 KB/sec, approx 318 Kbps, 0.31 Mbps
2nd 512K took 14297 ms = 35.8 KB/sec, approx 295 Kbps, 0.29 Mbps
3rd 512K took 22297 ms = 23 KB/sec, approx 190 Kbps, 0.19 Mbps
4th 512K took 13218 ms = 38.7 KB/sec, approx 319 Kbps, 0.31 Mbps

Overall Average Speed = approx 281 Kbps, 0.28 Mbps

1st 128K took 2047 ms = 64031 Bytes/sec = approx 533 kbits/sec
2nd 128K took 2547 ms = 51461 Bytes/sec = approx 428 kbits/sec
3rd 128K took 2703 ms = 48491 Bytes/sec = approx 403 kbits/sec
4th 128K took 1813 ms = 72296 Bytes/sec = approx 602 kbits/sec

It's no surprise I'm in my 30 day cancellation period; the service in terms of speed, amongst other things, has been poor in the evenings for well over a month now.

sorry sore throat

Better call the plumber, seems to be some leaks somewhere
Thanks for the info, shame you couldn't be more vague though
