Ilyes,

I was having terrible problems with F10 on my 4+year-old laptop, and I 
am now running rawhide from a F11 Beta install, and nearly all my 
problems, including disk & display performance problems, have gone 
away.  I hope I am not far from the truth when I say (at least as I've 
been told) Xorg in F10 had some issues, almost all of which are fixed in 
the version that is scheduled for F11.

Try the F11 Beta or Snapshot Live CD on a USB stick or bootable flash 
memory, like I did.  You'll probably notice some great improvements.

Note:  I've /only/ had these problems with F10. F8 & F9 never gave me 
performance problems.
