[c-nsp] Maximum Throughtput Cisco Router

[Orr, Jeff B.]

Off the top of my head with CEF a 3925 is good for 450mb. This is with no features. 

Depends on what you are running. I have several 3925 with a DS3, handling QoS marking, queuing, GetVPN. When the ds3 is at 25mb I run about 50% CPU, and 80%+ at 45mb. I turned on fnf (flexable netflow) on the ds3 and killed the router at 99% CPU. 

WCCP for WAAS is a huge performance penalty as well. 

A big difference is a TDM circuit vs Ethernet. The serialization occurs in CPU and is a penalty.

I am in the process myself of upgrading to 200mb MPLS metro-e. We are going with ASR1001. 
Honestly, I probably will be using ISR for branch only. I'm sticking with ASR in the data center.
