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 net.isr.direct and net.ip.fastforwarding are doing similar things. Should they be used together or rather not? Thank you! Markus
