Cache misses for small packet flow due to the fact, that the same data
is allocated and freed  and accessed on different CPUs will become an
issue soon, not right now, since two-four core CPUs are not yet to be
very popular and price for the cache miss is not _that_ high.

SGI does networking too, right?

Sslab deals with those issues the right way. We have per processor
queues that attempt to keep the cache hot state. A special shared queue
exists between neighboring processors to facilitate exchange of objects
between then.
