Improving network filtering performance with Bpfilter
(free link) https://lwn.net/SubscriberLink/1017705/ca0af831379ca794/

From servers in a data center to desktop computers, many devices communicating on a network will eventually have to filter traffic, whether for security or performance reasons. Bpfilter is a project that allows packet filtering to be done with BPF, which can be faster than other mechanisms. Even small performance improvements in this area can lead to significant gains.
