[Update] A request - do NTL traffic shape? (Yes, they do) - Page 7

RXP · 10-10-2006, 05:30

I've noticed my internet stopping to a crawl soon as bittorrent/emule is up. Even when it's downloading only at 20k up and down. Hmmm, the reason I got onto NTL in the first place was that it wasn't shaped. I woudln't mind if they just shaped P2P between 6-11pm but HTTP is a crawl too. (<1mbit on a 20mbit line). If they don't fix it within a month I'm out due to breach of contract, since I'm still on the 12 month contract.

Hi All,

I was wondering if there is any definite confirmation on whether the Traffic shapping is happening on just the 10mb connections or on all speeds?

I ask this as the traffic shapping seems to be affecting WoW pretty badly and if it is only on the 10mb speeds I would rather drop down to 4mb and have a stable WoW game

When I was on 4mbit, soon as I started bittorrent whatever it was uploading at the net would slow down. So it's not just 10mbit.

Just read through the posts, you say its only been what a month that this has been happening?

Try a year nearly...

ziggycat · 10-10-2006, 15:00

RXP your right, they have implemented this so that as soon as p2p connections are established the entire service is shaped making web browsing very very slow.
Still unable to test 4 meg, I asked them to downgrade my service last Friday, I've spoke with them 5 times since and have now been told it's been done but won't be effective until tomorrow (Wed) six days after I first requested it, I did managed to blag them for 3 months half price ÃƒÆ’Ã¢â‚¬Å¡Ãƒâ€šÃ‚Â£12.50, just over 30 days of my contract left with them and I'm off.
This has only been happening for two months, sebs if you've been having problems for a year I suggest you get your signal levels checked.

Anyone who is still on the minimum 12 month contract and wants to leave just tell NTL that the traffic shaping is a breach of the original contract.

Thats probably more likely to do with your upload is set too high in the p2p app rather then shaping, keep it no higher then 15-20kB on 10meg connection and halve it on 4meg.

ziggycat · 11-10-2006, 09:58

Its got nothing to do with upload speed being set to high, as I stated earlier I cap all my p2p uploads always leaving me with at least 25% of my ul bandwidth available for tcp acknowledgements.
They have implemented this so that it shapes all your service as soon as p2p traffic is recognised.
I'm sure you'll see more and more people complaining about very slow web browsing when using any form of p2p.

RXP · 11-10-2006, 11:37

Lol I can upload at 70k but cannot upload on P2P at 11k? It's traffic shaping not uploading.

Well I don't know about bittorrent, but from around 4-5pm every day until midnight, my web browsing slows down unbearably.

I'm heartily sick of it. I emailed NTL about it and they asked me to phone them. I know what the phone call will be, a bunch of rubbish about rebooting the computer and box, firewalls etc. Its none of those, its bloody NTL.

Overall Average Speed = approx 1479 Kbps, 1.44 Mbps

I just posted in another thread, but this:

http://www.chetnet.co.uk/articles/in...x_v2&id=32&c=5

site has made a remarkable difference to my browsing. Its now much much faster.

The overall speed is still ****e, but at least pages load properly now.

The next question then to NTL slowband should be why do we have to do that. Why can they not fix the system. ?

They have had years to sort out their proxy servers, You would at least think they would have found someone capable of fixing them by now.

When I signed up to NTL, I was told:

"We are not going to start traffic shaping. We are going forwards, not back".

That was a condition of me signing up for 12 months. Having said that, NTL are still the best of a bad bunch IMHO. Honestly, you think NTL is bad, try ADSL...

Anyway, the trick with P2P is to limit your upload speed to 10/11k. Anything more and you get severe slow-down. I have tried everything, even built a pfsense based router and tried traffic shaping, but basically 11k is the maximum for P2P on NTL.

I'm on 10 meg, but it applied back when I was on 2Mb as well.

I think maybe 15k is where the traffic shaping kicks in, so 11k+overheads... or maybe it's just generally NTL crapness, who knows? But you can upload to your web space at 50k/sec and have no trouble browsing on 10 meg, so it's definately P2P related.
