Routing SMP benefit

Currently running a few routers on 5-STABLE I have read the
recent changes in the network stack with interest.

A few questions come to my mind:

- Can a machine that mainly routes packets between two em(4)
interfaces benefit from a second CPU and SMP kernel? Can both
CPUs process packets from the same interface in parallel?

- From reading the lists it appears that
and net.ip.fastforwarding are doing similar things. Should
they be used together or rather not?

Thank you!
