I recently installed Fedora 12 on my machine. I think it's the fastest Fedora version I've used. But I was wondering whether I could make it run faster than it already is.
It probably feels sluggish because of the default desktop environment (GNOME) which uses a fair amount of memory. You can easily change your desktop environment though. I'd recommend Xfce for a full DE, or if you really want to use minimal resources, a lightweight window manager such as the *Box variants (Fluxbox, OpenBox, BlackBox), or xmonad or ratpoison on top of X itself would be good. It doesn't have to look horrifying either, here's a screenshot of openbox:
