Yeah - Cisco would like to know why as well:

I know ;-)

But: This is not a churn problem, it's a problem of slow CPUs in
allegedly big-and-fast boxes. I'd like a NPE-G2 blade for my
76's, as RP. Still, this is getting off-topic.

The MSFC4 in the RSP720 has a 1.2GHz 8548 PPC whereas the NPE-G2 has a 1.67GHz 7448 PPC.

I'd guess the performance isn't all that far apart, especially as the MSFC4's processor isn't doing any forwarding.
