I have changed to Linux recently. Here I am experiencing very slow Internet connections for applications like apt-get and Firefox browsing through proxy (download speed in Firefox is pretty normal). My Internet connection uses a proxy system ( I think SQUID PROXY)with username and password authentication. I have tried to put proxy settings in apt.conf or .bashrc or like adding proxy environment in /etc/sudoers. Git clone speed is pretty normal. At the same time the speeds are rocketing 100 times than linux in windows. I hope there might be a solution. Please help... (tried it in fedora also...Same problem)
