What my understanding is that CEF and Fast Switching happen inside the router i.e. b/w input and output interface, once the exit interface (route) has been determined. So, routing protocol does not have much to do with it. However total speed is switching+convergence time based on your routing protocol and other variables such as CPU etc. Performance improvement depends on your configuration and access lists etc. In addition to enable it globally, you have to enable CEF per interfaces, as you might know.

If one was to enable CEF on this box (over fast switching), would one expect to see any/much performance improvement? This box does not support dCEF (72xx chassis).
