gnn has done a lot of research on *nix networking and the conclusion is "single sockets are always faster than multiple sockets". There's a huge performance hit when trying to process packets as fast as possible and you throw NUMA into the mix. Remote memory is accessed more slowly, and pinning work to specific CPUs is non-trivial.
