In http://ubuntuforums.org/showthread.php?t=2043665 Post #10 the use of a non-pae kernel is recommended for users of old computers. It is supposed to use less memory and run faster. I have an old Compaq Presario 2100 that always has cpu usage of more than 50% (doing nothing) and will be at 100% usage very often, leading to sluggish performance. I am running Ubuntu 12.04.1 Precise Pangolin.
Does anybody know how to set up for using a non-pae kernel in 12.04.1? Does anybody know of other things that will make the computer less sluggish? Note that I am already running Gnome Classic (no effects).
Thanks in advance.
