•The Policy Feature Card (PFC) and any
Distributed Feature Cards (DFCs) provide hardware
support for policy-based routing (PBR) for
route-map sequences that use the match ip
address, set ip next-hop, and ip default next-hop PBR keywords.

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.
