Bittorrent Download Slow

[Eliecer Brathwaite]

Wehave been downloading using Bittorrent for the last year with no problems. However for the last couple of weeks my download speeds have suddenly, regularly been below 20 kbps, and are often below 5 kbps. My connection often has allowed for speeds of up to 150 kbps depending on the popularity of the torrent. I even upgraded to version 7.2.1 and nothing improved. I have set my firewall to allow Bittorrent but that did not help either. I am working with torrents that have many potential seeds over 3000 in some cases but rarely get more than 50 - 60 actually available. Even with those my download speeds are under 20 kbps, before such numbers would have given much faster downloads. I am running a Compaq Presario with an AMD Athlon X2 processor. Any suggestions would be appreciated.

I tried the setup and got the following: For the bandwidth I got two error messages either something about a socket not being something as the message was not complete, or the message Connection failed error:Timed out(1006010).

With the download speed test I got a speed of about 30 kbps, much slower than our fastest torrent in the past. I currently have a torrent downloading with 45 available seeds, and a speed of 20 kbps max.

I have my router properly configured and have a 25MB/s downstream and a 5MB/s upstream connection on a very clean 3.4GHz dual core computer running Windows XP SP3 with about 30 processes running. (I am an IT tech and I know what I'm doing.)

No global throttling is enabled, up or down. Upstream speed is throttled on each individual torrent at 150KB/s (but I have experimented with everything from 1KB/s to no throttling - many points in between. I've also experimented with a wide range of connection # limits. I've found that I get the best results with both Global Connections and Connected Peers Per Torrent set at 9999.

Also, doing your upload limit per torrent instead of globally is probably part of your problem. And your connection limits are a massive contributing factor. BitTorrent doesn't work well when trying to maintain connections to that many peers at once.

Thanks for the response. I'd really appreciate it if you could give me some advise in that regard. I have experimented with lots of different limits and I seem to get the best results with higher numbers.

Also, the ratio of CONNECTED seeds to CONNECTED peers is part of my frustration. Certain torrents, like torrent #2 above, simply won't connect to more than a handful of seeds, even when there are thousands of them available. Why is that?

I just don't get it. Certain torrents are like this. I've been connected to this thing for over 12 hours. Why do certain torrents lock you out of the loop? That is supposed to be the whole powerful thing behind torrent technology - that everyone gets in on the bandwidth, and the more you share the more you get in return. Certain torrents like this one seem to shut out certain peers no matter what that peer does. Anybody know why that is, and if it is possible to "break in" so that your not left on the sidelines with 56K dial-up speeds on a 30Mbps pipe?

If I am "using an upload limit that is too high"? I just told you that I am using the settings you recommended with more available downstream throughput than you have (25MB/s). I am not dividing my connection too many ways, as I am only downloading one torrent. And neither my internet provider nor my security software is interfering. As I stated multiple times, certain torrents come down at 4 and 5Mbps with no problem.

I've covered all of this multiple times. I appreciate your willingness to help, but frankly it does get a bit frustrating when the answers I get back clearly disregard points that have been covered. I'd really appreciate some answers that are more than shots in the dark.

Try with the apply rate limit to uTP turned off. It may keep your connection pinned, but at least uTP will attempt to claw itself back when you want to do something else. There are ways to fine tune the thresholds that uTP uses to slow itself down in the advanced settings if it's still a problem (the two net.utp target_delay settings, I run them both at 80).

I have a problem kinda the same. When I start a torrent, the upload and download fly, but after a few hours the upload speed is at five times the download speed. When I limit the upload speed to the same as the download speed, then the download speed increases at 5 times for a while, then slows to a lower speed than the upload speed. I have tried everything and nothing works ( kinda like they are taking advantage of my fast connection and leaving me sucking along at five times slower ). I think the torrent sites are doing this!!

I timed both with a stop watch, and checked connetion speed and pinged both computers and thay are close to the same, with my computer showing a little faster, but torrents slower. I have tried to clear my feed list so only one torrent is downloading/uploading. Still the same thing after a while ( upload fast download slow ). I am woking on this problem at the moment. Thanks, Robert

Hello, when I'm using torrent on my machine I realize that the whole network is slow.

Before installing OpenWrt on the router this did not happen...

Today, I can't even use 100% of my connection on my client torrent.

I enabled SQM and saw no network improvement or stability.

It is noticeable in the speedtest that all devices have a very low speed when the torrent is active, even without the torrent using 50% of the network.

Hello, you need to set upload and download limits at about 90-95% of max, for sqm. Looks like you currently have them set to zero. Also will depend if your router has enough CPU to shape traffic at those speeds.

SQM Details If you want to set up SQM to minimize bufferbloat, you should start at the SQM Howto page. The remainder of this page gives some of the theory behind SQM, should you be curious about it. You should also check the Bufferbloat site for...

also, there is plenty of documentation in this forum how to setup sqm, please read them first then you can play with this or that recipe until you find your best version which is specific to your usage profile. do not assume a recipe is working for someone it will automatically work for you too. sqm requires quite a long trial and error process till you find it useful. or even you'll find that sqm will do more harm than help - this can also happen. if owrt with sqm, or owrt without sqm or the factory firmware is better for you, only you can make that call. good luck.

As well the seeding alternates between the torrents I have going for some reason. When the first torrent starts seeding it goes around say 5 kb/s then starts getting slower until its at 0 kb/s then the second torrent starts getting a seeding speed and goes around 5-6 kb/s and then goes slower and goes to 0 kb/s. When thats at 0 the first one starts again. Its been on for at least a day and one of them has only 42.7mb uploaded and the other is 278mb. My ratios are going completely down the hill!

I dont think there is an upload limit set. I did have it for 40kb/s when seeding goal was met, but I unchecked that. I also had ratio limit set at 100% but changed it to -1 because I read that was unlimited and thought it might fix it but it didnt.

I couldnt seem to find the speed test there. Which link do I go to? I also have no idea whats good and whats bad, but on one of them it says there is for seeds 0 of 285 connected (401 in swarm) and for peers it says 2 of 57 connected (31 in swarm)

I just disabled UPnP although I'm not sure if it made any difference. And I have no idea what the half-open connections is. I feel dumb. lol I have no idea if my winxp is patched either. I do have SP2. is it a patch from windows or utorrent?

I fixed the download speeds. I'm getting 250-450kb/s now on average. My upload speeds are pretty slow tho. I dont know if I just didnt put the right settings for that or if theres not enough people to take the file from me.

One problem I'm having tho. I think the speeds are too fast for my modem now. After a while it will lose connection. The popup in the taskbar comes up saying that network connection was lost is reconnecting. Then it will start downloading again after its re-established.

Problem : I live in a country where carriers provide mobile data plans which they offer for 5 dollars; I get the 10GB "night time data package." So I tried to download some torrents from my PC using iOS personal Hotspot feature. But all the time I try to download a torrent it gives like 1KBps speed or less.

I've changed settings in uTorrent according to my internet speed but it gives slow speed. When I try to download large/small files directly from a website (web server) it gives full speed my carrier supports like 40Mbps. I have the problem only when downloading the torrent.

What I've found so far : I thought (still think) that would be a restriction with iOS and contacted apple support team and asked them about that. But they said iOS doesn't slow down speed when downloading a file through personal hotspot and said probably my carrier throttling my speed. But still I think iOS slows down my Internet speed because of a clear reason which I've explained below. So I want know whether iOS slows down my Internet speed when I downloading a torrent or my carrier throttling when downloading a torrent.

I don't know of any traffic shapping or bandwidth throttling capabilities of iOS. Technically, you would need stateful packet inspection to be able to detect Torrents and then slow them down (traffic shaping); this is found on many advanced routers and most definately not in iOS.
