But isn't this an apples and oranges comparison given the original
question? Assuming the border router is going to the WAN, first, the
WAN link is probably much slower than the LANs and is going to be the
limiting factor in transfer, not the forwarding speed of the router.
Border routers may also need to do significant policy enforcement,
security, QoS, accounting, and other processor-intensive functions.

Again, what problem are you trying to solve? Raw forwarding speed
makes no difference if the outbound link is significantly slower than
the inbound.
