Core 4 or 5 it was significantly faster that F8. I remember day when I
turned off Compiz (maybe in F6) and said "Yeah, this is pretty fast".
Now I'm back in Compiz days but without Compiz. I don't think disk
usage is main problem (but in some cases yes - command yum update
always bother me in this case) generally. It looks like code become
slower and slower. And last team of really good programmers stucks
with improvements like preloading or compiler optimization. I'm not
against features. But We really should not add features and improve
stability without care about code speed and quality. Looks like I have
to switch from gnome to blackbox or fluxbox. This will solve my
problem. For now. And after two years I will start using runlevel 3 by
default...
