F16 slowness

[Lucas]

I can confirm this as well.

But, I have two kernels: kernel-3.0.1-5.fc16.i686 and kernel-3.1.0-0.rc4.git0.0.fc16.i686
The system works much slower with 3.1.0-0.rc4.git0.0 then with 3.0.1-5.fc16, especially 2D graphics 
is much slower.
I am waiting for the normal kernel (not the git one) and if then this slowness persists I will open 
a bug about it.
I also do not have any errors. Except may be the udisk can't pull sr0 cdrom with 
3.1.0-0.rc4.git0.0.fc16.i686, although my selinux policy is permissive.

Thanks.
