This is a pretty weird problem I'm having with torrents/p2p. A normal connection online give me speeds of 3500-4000k/s. As soon as I open up either Azureus or utorrent and start downloading (even at speeds below 1k/s) my connection speed drops to about 1000k/s and lower, usually around 500k/s as it starts to download faster, or with two computers running p2p software.
WTF is going on? I ran soooo many speed tests with my computer connected to the cable modem directly, then downloading files normally (via firefox), then torrenting, and the torrent drops my speed. I did tests wired and wirelessly. I eventually had three computers online wirelessly with normal speeds until 1 or 2 ran a p2p application.
Here's my info:
Earlink Cable Ericsson PipeRider cable modem
Linksys WRT54G v4 Router
Windows XP Pro (no service packs)
ZoneAlarm firewall (NAT tests OK)

hey , firstly are you using a private tracker ?
2. have you changed your port number to something above 50.000?
3. have you forwarded the port on your router ? if not try this link http://www.portforward.com
4. have you configured your bt client ?

1. I use mostly public trackers or whatever trackers come with the torrent.
2. Is that 50,000 or 50? With Azureus 6881 usually works, and with uTorrent its usually 34000+.
3. Whatever port I use, it is forwarded through the router and opened in Zone Alarm.
4. Which settings exactly? I've tried changing some based on connection speed (open slots, connections, etc.) but that hasn't done anything.

A lot of people say differently, but I would try setting your upload/download unlimited. Also, how long did you wait? Sorry if my questions seem stupid, but some people are clueless, and I wanna help. Also, try a different client?

In utorrent, they're already unlimited. I've tried uTorrent, Azureus, and BitComet with the same results. Right now I'm downloading at around 25-40k/s and my internet speed went from 3000+k/s to 800k/s. The speed of the net connection stays low during the entire download.

you need to change your port number to 52136 or something similar because isp's throttle the speed on 6881 , every torrent site says do not use that port number it affects download speed

I tried changing it to a port over 50,000, shut off DHT and UpNP (in utorrent and router). I've even tweaked my MTU. Still no luck. I'm going to update my Linksys router's firmware to HyperWRT Tofu soon and see if that will do the trick. I was also told I should cap my upload speed at 80% so I'll try to find out what my upspeed is and play with that. I have been told there may be a problem with my cable modem itself.

It's possible it could be the modem ,but you are getting a reasonable speed so far .Prob is the firmware in the modem .As of capping i dont cap any of mine at all unless im seeding more than 5 torrents . ah ive figured it out , its the public tracker you need to get on a private site for a better seeder ratio pm me your email ive got demonoid invites try that and see if it gets any better

I fear that the problem is not with his modem firmware. I am using a different modem - 2wire 1701HG Gateway with firmware version: 3.17.5. So, we use two different modems from two different providers. I have SBC Yahoo DSL vs his cable connection. I run Bit Comet on random ports. My DSL line checks out very nicely - this assertion is supported by a line test found at http://www.dslreports.com/quality/nil/1940087 . I am able to max out my 3000/512 line and sustain the full bandwidth for days using NNTP if no torrent applications are running. However, if I run a torrent application my maximum throughput becomes 1200 kbps during the day and I am unable to sustain even that speed (My torrent up and down stay in the 300 to 440 kbps range most of the time - the bandwith maximization comes from use of other protocals - NNTP or FTP). I was able to replicate this issue at the home of a friend in another town who also subscribes to SBC DSL using their computer and Azereus as the Bit torrent client. However, when I took my laptop to my neighbor's place- he has local cable connection - no issue. The evidence leads me to the conclusion that my torrents are being throttled either by the 2wire gateway or SBC Yahoo most likely by traffic shaping torrent streams. Has anyone found a solution to torrent traffic shaping?

what is your upload speedlimit ? to download @ 4000k/s you need a pretty good upload speed ! so if you max upload speed is like 50k/s and you are using 40k/s you wont be able to get a good download speed
by k/s i mean kilobytes per second
Due to the way TCP works, when A is downloading something from B it has to keep telling B that it received the data sent to him. (These are called acknowledgements - ACKs -, a sort of "got it!" messages). If A fails to do this then B will stop sending data and wait. If A is uploading at full speed there may be no bandwidth left for the ACKs and they will be delayed. So due to this effect excessively high upload speeds lead to low download speeds.

I believe that there has been a digression from the topic. The important things that we may take from circleda's original post are:
1. Speeds for downloading using conventional protocols are normal until p2p applications are used
2. circleda asks for possible causes
The cause of lowering the ceiling at which one may download once a torrent is engaged is most likely traffic shaping. This issue is well known to our friends on Rogers Cable internet in Canada. The issue has become so pervasive that BitComet 0.60 has added the following feature: Protocol Header Encrypt (Anti BT Protocol filter). This option can be found under Prefernces -> Advanced -> Connection. I have personally used this option to max out my download speed on my line using a combination of NNTP and BT.

that doesnt help if you are using all your upload bandwith already and trying to download, you still wont have enough upload bandwith available to download at 4000kb/s, i bet that it is also the case if you download from http and using all your upload speed somewhere else, still no full speed.
Try getting a download/upload meter it will give you an idea how much upload bandwith is required to download at 4000kb/s
Limit your upload speed in the bittorrent client to get full download speed

An Earthlink cable account with typical speeds of 3500 to 4000 kbps will almost always come under the advertised speed of 6000/386 source: broadbandreports.com. So, max torrent upload speed should be set around 308 kbps. circleda says that he has tried various setups on several BT clients. So, I tend to doubt that he overlooked setting an appropriate maximum torrent upload rate. However, the symptoms described appear indicative of traffic shaping. Fortunately, we have a remedy for that malaise.

You need people to actually connect you know.. just sticking a torrent on a site doesn't do anything unless people can connect. You are then at the mercy of their download speed capping. Some trackers themselves use traffic shaping to force a 1:1 ratio. I avoid those.

That is probably traffic shaping. Your ISP is cutting your juice. They are all probably doing it to some extent some more than others. There is a massive AI application that monitors the traffic if it 'thinks' you are using too much resorces it will slow you down. Some just throttle some will attack nodes. They can forge 'I am done' packets if you are not encrypted, they can block firewalls and listener ports etc.
