Connection slows down.

[sentimetal]

I'll start with:

Yes. I have followed the speed guide, looked at the tweaking guide, and have followed any advice related to my problem.

utorrent is allowed in my firewall, which is only the XP, SP2 Firewall. I don't need to port forward, as I am directly connected to my internet's modem.

My problem:

It started ~3 days ago. I noticed that whenever I downloaded more popular torrents from popular sites (think ... axxo), that my connection would lag. Not only that, but the downloads that I was once getting 500kb/s down/300kbs up were now getting 30kb/s down/20kb/s up. I tested a private Asian movie tracker to see whether or not it was the trackers just giving me crap speeds, or if my connection was sucking, but the Asian tracker seems to work just fine. I tested a public Anime tracker today, and it slows down my connection as well. I also tested torents with few seeders from the first tracker that gave me problems... it does this as well, so i don't think I'm overloading my connection by downloading largely populated torrents. Besides, previously, I was able to download from these places with no problems.

I want to blame it on the more popular trackers, but how can a faulty tracker slow down my whole connection like that? Simply trying to download a torrent from them makes everything go slow. ; / I have my max connections per second set to 100.

Any ideas? ;/

If you have LPD enabled, that may do it with the multicast. If you have tried the guides fully though you will have already turned off DHT and LPD.

What version of uT are you running? And did anything change during that time (3 days ago) related to your computer or computing?

[sentimetal]

DHT is off. Always has been (I've even enabled it to see if it helps). I didn't change any settings in utorrent prior to the slowdown. Same with LPD.

I thought:

Disable DHT and UPnP, reduce half-open connections (net.max_halfopen) to 4, lower bt.connect_speed to only 10, set net.low_cpu to TRUE.

would help, but it didn't.

Version 1.7.5 of utorrent. And no change to my computer's settings at all.

Try reducing global connections to only 40.

Also disable Resolve IPs under the PEERS window. (right-click in the window)
