Unless I am misreading this, he did not hit a wall. What he did was
test a design that was scalable to multiple cores and show that the
two core version could not go beyond 700k pps. The next logical question
is how much more can you push with larger numbers of cores. The key
thing is to use a recent Linux kernel that can share interrupts among
multiple cores and to run it on a CPU using MSI interrupts. Since this
was written up in January of 2007, 

There are people who use Linux for load balancing who also are working
on finding how well it can cope with 10G of traffic and they have some
anecdotal evidence of 800k pps.
