RHEL (and thus CentOS and SL) are designed for stability.  They are
based on Fedora 6 in terms of new features/optimization/technology.

More recent Fedoras have more bells, whistles, and optimizations, so
might run faster (if the new features don't consume all the newly freed
cycles), but are more prone to fall over.

Are you using it for a desktop or a server?  I think most all the
performance enhancements in recent Fedoras are aimed at the desktop
(which is where most users notice speed), rather than at the kernel
level.
