NetworkManager is fine for something like a laptop with a 'varying' network environment, since it interfaces with the gnome-network-manager applet, which gives one a little GUI thingy for selecting this or that wireless hot spot, etc. For a machine with a *fixed* network connection, NetworkManager just gets in the way and trys to be excessively 'clever'. > > The performance of the machine seemed to be better with the newer > kernel, which is encouraging.
