I suspect that the web server's CPU usage will be pretty high (almost 100%), so C-state tuning may not matter as much?
EDIT: also, RSS happens on the NIC. RFS happens in the kernel, so it might not be as effective. For a uniform request workload like the one in the article, statically binding flows to a NIC queue should be sufficient. :)
