Since the ASR does most things in hardware, most of the basic features 
shouldn't hit the RP unless something is configured wrong.  Normal QoS 
and NetFlow shouldn't be a strain on the RP (except for Netflow 
exporting).  I don't know about the more unusual features like WCCP. 
You would probably fair far better on the ASR than the 7600 or 7200 for 
those I imagine.  That's my limited understanding of the ASR though. 
I'm looking at them as a replacement/upgrade for a few 7200s on our network.
