utorrent makes my internet connection suck!

[benrober]

I use utorrent instead of Azureus because it is light weight and quick, the one drawback that I have noticed since I have been using it, which has been about 6 months, is that it slows my internet connection down a lot, almost to an unusable state.


For a while I had my upload limited to 10Kb/s with utilized 22% of my upload limit from my ISP of 45Kb/s. We have Comcast and we upgraded to their "blast" service which gave us a DL rate of 16MB/s and we have tested our upload to be around 350Kb/s so there should be no problem with having the UL rate at at least 45 or 50.


Why is my internet so slow when I use utorrent?

Comcast is currently under investigation about P2P usage and their network shaping. Your probably being capped on your network because they have identified your traffic as hoggish and are slowing you down!

That may be the case, I probably should have also included this in my previous post, my roommate uses Azureus more than I do and he has no problems. I have also used it and it does not effect my connection like utorrent does. I do not want to switch back though. utorrent is all set up and work well, other than the obvious problem.

I run Utorrent also, and what I've found is that if I throttle it back to 100kbps down and 30kbps up, it runs stable. Utorrent is a hog on resources any way you shape it. It slows down my computer if it is running ( 1.5 gb ram w/amd 2500+ processor ). I tried different routers because it would reset my connection or freeze it up because the router couldn't handle all the requests. I find that having it at the settings I posted, just about anything I want to download will be here by morning if I let it run over night and there are enough seeds to give me decent bandwidth. ( this was on comcast, I'm currently with Qwest DSL and haven't had any issues with it with these settings either ). It also allowed my wife to play here MMORPG while it was running.

Routers may track old connections for a long time. Thus slowing down you connection. Look into DD-WRT and scripts...

P2P applications are "riskware" Make sure you have no hijackings...


If you use DD-WRT, then you may want to try one od the following "start up scripts".

echo 4096 > /proc/sys/net/ipv4/ip_conntrack_max

¿ Best Router For Torrents ?

I will give this a try. Thanks for the help.
