cools

Thanks for the hint! As soon as you brought it up I remembered I installed nod32 around 10 days ago and that the problems kind of overlaped with the installation. I was certain I disabled the real time protection during the tests but obviously I didn't. So my problem's solved. Thanks again...

I am having the same problem as AJZ and Daimonion. I have a 12Mbit/1Mbit connection and upload limited to 70% of my limit. Within a few (15) seconds of starting utorrent I practically can not surf the net anymore due to a significant slowdown even when the upload speed is even less than 10% of my limit. As soon I turn off the utorrent program, the net again behaves normally. Ports are open but it isn't the router I think cause it all acts normal when the utorrent is off and I haven't changed any router settings for a while and everything was working ok sooner. When I tested the max dl/ul speed of my connection with utorrent on or off it is practically the same, but it seems as ping time increased so much that web pages open so slowly. The problem still remains with 1.8 beta 8205, and I don't know what else to try (net.max_halfopen is the default 8, both dl/ul and all bandwidth settings in program are even lower than offered after finishing the speed guide in utorrent, DHT is disabled).
