Does anyone know how the newer architecture of the ASR1k ESP compares  
to a 7200 NPE-G2 in regards to 'all services enabled' performance? If  
I recall previous discussions on this list, it's fairly easy to  
overload the CPU on the NPE when you start enabling QoS, NetFlow,  
WCCP, FPM, etc. Do the ASR1k ESPs do this any better?

The ESP data sheets show a 50-60% pps performance decrease with  
'commonly-used features' enabled so I assume its fairly similar, but  
the ESP provides a higher maximum throughput so enabling features is  
not so much of an issue? At least with the ESP, Cisco are providing  
some theoretical maximum vs standard performance figures.
