CEF and PBR

Hello,

we are trying to understand if PBR is CEF switched or not. Based on
this CCO document, PBR is CEF switched:

http://www.cisco.com/en/US/docs/ios/12_2/qos/configuration/guide/qcfpbr.html
#wp1005373

Is this true? We see another DOC that contradicts and claims that by
default it's process
switched and can be configured to be fast switched:

http://www.cisco.com/en/US/docs/ios/12_2/ip/configuration/guide/1cfindep.htm
l#wp1001538

Here's the main question. Our PBR is configured to match on ACL that
matches TCP ports
(not IP addresses). Would this traffic be process switched or CEF
switched? I'm told that it would be CEF switched. I don't understand
how CEF tables can store TCP port information.

Thanks!!!
