I did not checked how netchannels and userspace stack behaves on SMP
just because I do not have SMP test machines. Getting into account that
netchannels have smaller number of locks (actually only one to queue
skb) compared to sockets, it should not behave worse, but I did not test
that.
CPU usage was obtained via /proc/$pid statistics.
