I believe it is system specific, I'm seeing a massive amount of
slowness on my eeePC 901. Its a standard first gen Atom netbook. I see
high CPU from ksoftirqd/0 (pretty much all that should be idle) and
quite high CPU from some btrfs processes. gnome-shell takes for ever
to load but I think that's more the underlying kernel stuff. I've not
had time to try older kernels as yet.

I have btrfs on both root and home partitions, not sure if that might
contribute given the associated processes featuring in the top
processes using CPU. Its a mostly clean install. I had to do a minimal
F-15 install, yum upgrade to minimal F-16 and then install X, gnome
etc due to various issues with the F-16 installers I could find.
