Hah, keep drinking the cool aid!  I have a pair of 6500s ready to fall
over at about 150kpps.  All WS-67xx LAN cards with DFCs.  CPU averages
60% and often maxes.  TAC says that this is within the parameters of
normal performance given the role as datacenter aggregation routers.

No netflow, no uRPF, no multicast, no IPv6, no BFD, no MPLS, no ACLs
in the forwarding plane.  Very basic OSPF, BGP, and MSTP.  About 2000
VLANs, 80% of which have associated layer 3 SVIs.

On the other hand, I have other 6500s with identical hardware
inventory and almost identical config where performance is a complete
non-issue.  I've seen a 6500 in a near-optimal situation switch
2-3Mpps.  I'll believe 30Mpps when I see a 7200 NPE-G1 hit 1Mpps :)
