We run 7206 NPE-G1s on some GigE peering points. At about 800Mbps of aggregate Internet traffic (inbound + outbound, as measured from Cacti) the CPU sits around 70%. Setup: - inbound and outbound Internet-facing ACLs (50 lines and 25 lines respectively, turbo ACL) - Inbound Internet-facing policy-map to remark DSCP (references 7-line ACL) - minimal routes via BGP (approx 1500) - 15.1 SP train YMMV, but they work well for us in this scenario. With downstream-to-upstream traffic patterns of approx 7-to-1 the GigE and CPU will peak out at about the same time. Side note - our G2s at that same 800Mbps traffic rate run at approx 60% CPU.

Or assuming your using an Ethernet of some sort as your upstream connections you could grab something like a CCR from mikrotik for < $1k and sleep easy knowing you're only using 6% of it's capacity.

Test and see. I'd just receive the full table anyway but filter them out, letting only the default routes go into the RIB. This should streamline your FIB. As I say, you lose outbound load balancing and your redundancy becomes all-or-nothing, but you save a few cycles. Again, I wouldn't recommend any of this because of the drawbacks, but along with other recommendations that others have made, like Turbo ACLs, it may buy you some time.
