The techniques used to increase IPSec network performance are often kept as secrets because they act as a competitive advantage and a lucrative product offering. This talk transparently presents a technique for massively boosting IPSec performance that is simple to implement (less than 200 lines of C), and based entirely on open-source work. An early Proof of Concept (POC) implementation showed an increase in p99 throughput by 412%! This talk will take a deep-dive into how it all works, covering: the implementation, the pros and cons of the design, and an analysis of benchmark results. As transparent encryption becomes more crucial for securing data in transit, we hope this talk will enable users required to use IPSec for compliance or infrastructure reasons to learn how to speed up their network without having to compromise their security.
