Especially if they're directed at the router itself, at some point, sure - though the ISR2 certainly has more horsepower than the original ISRs, and I've personally yet to witness an ISR2 being DDoSed, so I've no feel for the specific numbers.  Features also play a role.

This isn't to say that the ISR2 isn't a fine router - but rather that one must be cognizant of performance envelopes prior to deployment in order to determine suitability to purpose.  One can't reasonably expect vendors to exceed their design constraints in any type of equipment.


One can and should test the specific performance envelope of any prospective infrastructure purchase, of course.
