I think (correction welcome) that it only works in hardware based upon  
matching an extended ACL - any attempt to do things like match on  
packet size, etc. results in software switching.

PBR by its nature is operationally brittle and ugly; if there's  
another way to accomplish one's goal, it's generally best to pursue an  
alternate method, if at all possible.

         Unfortunately, inefficiency scales really well.
