After installing FC3 I was disappointed by the user interface speed in KDE. I am not certain if it is because KDE and Gnome keep getting bigger and more bloated. I tried switching to Gnome but the speed just wasn't there either. In KDE Mozilla Firefox would load slowly and the UI was sluggish. KDE was eating memory like crazy if I left it run all day. Hmm, what was I to do? My system is a little old: AMD 1.4 GigHz, Nvidia G2 graphics, 7200 RPM drive, 512 MB RAM, Audigy sound, etc...
I saw an article on XFCE on the web which suggested users switch if KDE and Gnome are just too slow on your system. I took the plunge and logged into an XFCE window session. At first I was totally lost since it was so different.
Oh my God! What a rush of speed... All the window lag went away in Firefox, Gimp, Nautilus. It was amazing. The system was so responsive. You have to try it out.
I took a screenshot showing the Nautilus file manager, Real Player 10, Gnome Terminal, Firefox 1.0, Firestarter Firewall, Gimp 2.0 running under XFCE. What a combo: FC3 and XFCE; amazing you simply have to try it. At first I missed my desktop icons and KDE application menu but then I just added launcher icons to the bottom XFCE panel. This is almost a F***ing religious experience!
