It could also that you are sapping your upload bandwidth. See http://www.azureuswiki.com/index.php/Good_settings#How_to_determine_your_upload_speed, particularly:
"Do not let Azureus (or any other program for that matter) take up the whole upload bandwidth. There needs to be room for overhead such as acknowledgement signals (ACKs) and resend requests. Downloads will suffer if these signals cannot be sent. Set your upload limit to about 80% of the maximum possible." I've seen my internet "die" when not limiting my upload bandwidth. -- bittorrent eats CPU - Only FF becomes slow. https://launchpad.net/bugs/24876 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
