NS1 Managed DNS runs on a large anycast deployment with approximately 25 POPs. We frequently need to assess new hardware for upgrades and expansion, and to do so, we must understand how our software performs. This presentation will discuss how DNS packets are processed on Linux, how the software interacts with hardware, and how to configure the software for optimal performance. We will also describe how we validate the configuration with benchmarks and share interesting findings from our latest testing.
