What is better? Use a SMP kernel or amd64 for network?

[Rafael Ganascim]

Hi list,

I have a doubt (don't encountered on google) about what is better for a
FreeBSD Router: use a 32bits SMP kernel or an amd64? I know that exists some
differences, but generaly, what is better and why?

I have a hardware with Xeon Dual processor.


Thanks,

Rafael
