Actually, at this time and the near future, "passing traffic" (i.e. the

working on making the network layer multiprocessor capable, but my
impression from watching the tech@ list is that this goal is still some
ways off. At the present time, only userland applications can and do
make use of the additional CPU cores.
According to the very first reports to come out of the s2k15 hackathon,
mpi@ & dlg@ *just* did a bunch of the critical work to get that started.

If I've got my timeline right, we're already post-5.7-freeze, so I
assume 5.8 is probably when us mere users will see a partially-SMP
network stack.
