This talk will outline the use of tools from the netsniff-ng toolkit and the Linux kernel along with a home-grown benchmark harness to characterize UDP DNS performance. These tools operate very differently from "traditional" utilities like dnsperf/resperf and produce very different results, possibly contradicting conventional wisdom that UDP on Linux is slow.
