Torrent Throttling

[Twigg]

I know theres a million threads about NTL throttling Torrents out there but none of them address my problem.

I'm getting fine downloading speeds of up to 350Kb/s. But the problem is, that whenever my torrent client is downloading even at fastest/slowest speeds my Internet surfing slows right down regardless.

Example
With Azureus on downloading at 14k/s, when I ping google.com I get

Reply from 64.233.183.147: bytes=32 time=2370ms TTL=244

Reply from 64.233.183.147: bytes=32 time=1799ms TTL=244

And when I pause downloading of torrents...

Notice the difference in 'time'

I've got Azureus encrypted, using an open port on my firewall that isn't the default port (1750 or something)

Does anyone else have this problem or can you suggest something?

What sort of network configuration do you have, straight modem connection or through a router?

The traffic throttling on the ntl side "should not" affect normal browsing.

Not a solution to azureus problem, but try this.

I find this to be the best client, browsing no problem

[Locky]

this happens no matter what client you use i am pretty sure it is not a bandwidth issue but the number of connections (the more connection e.g seeders and peers) then the slower the browseing goes, but jus sumet u gta live with u should jus download torrents off peak (when ur in bed leave ya pc on) that way other people are not suffering as a result of heavy download and you also have fully workign browseing wilst u on ya pc surfin tha net, jus my thoughts

what upload speed do you have set ? sounds like youre saturating your upload.

[RXP]

Lots of people experience this. It's something with the network. I can upload at 40kb a sec using FTP and browse fine. But if I even attempt >10k on bittorrent HTTP dies. Really annoying.

[Locky]

like i said, something to do with the number of connections..

[machead]

always have mine set up 25k upload other wise it does the same it also effects your download speed on the 10meg anyway

[Twigg]

I'm running my PC through wireless into a Wireless Router into the NTL modem.

I tried lowering the Upload to 15k/s and it vastly improved but its still very eratic compared to pausing torrents altogether.

Thats a royal pain in the butt.

Cheers guys.

This throttling is very, very, annoying.

I can sort-of understand them trying to do something about bandwidth hogs and am prepared to co-operate to a degree but throttled torrents are not what I thought I was paying for. It is especially irritating because my router software is a bit simple-minded and its own QoS attempts go completely haywire when the bandwidth rug gets pulled from under it by NTL's traffic shaping.

What seems to happen is that NTL will suddenly turn on throttling at the top of the hour - 18:00 seems very likely to see it occur. Have a look at this MRTG from last week; check out where the traffic suddenly gets chopped down to 25Kbs, Thursday is an obvious one also Monday and Sunday.

What can I do about it? Overall I don't use a lot of bandwidth (this week was a bit exceptional) but when I want it, I want it. I'm on their supposedly 4Mbs service, is it worth me telling them I will upgrade to whatever the next highest one is (will have to dump their expensive useless analog telephone service to compensate however) or do they just throttle everything down to that level no matter how much money you cough up?

Throttled or not, running torrents at the same time as anything else (even simple browsing) causes a massive slowdown, not necessarily NTL's fault.

They do give torrent traffic low priority during peak times (that is what the traffic shaping/throttling is, I thought) but browsing should be given higher priority so it shouldn't be slowed down. This is what I've read, anyway.

Limiting your upload speed and download speeds in your torrent client should make a big difference to browsing and anything else you do at the same time I think. If it's possible though I think the easiest thing is just to run torrents overnight.

In the end, I think you'll find it hard to find an ISP now that doesn't either cap monthly bandwidth or throttle. I personally prefer to have unlimited but throttled bandwidth than having a cap at 30 or even 10 or 5 GB per month. But then that's probably because I don't use bittorrent much

As has been indicated by Locky it's about the number of connections.

Me too

I tried to explain before but got shot down, the biggest killer with torrents/p2p is the number of connections, and after that the upload speed.

Generally there isnt a big reason to need to be so generous with uploading and I would set it to 50% of upload capacity at the most and keep number of connections as low as possible although it cant be too low since it works by utilising dozens of slow connections rather then 1 fast one sometimes.

Chrysalis, I went alittle deeper on this subject, as can be seen below.
