Description
In recent years, benchmarking tools have been extended to support new transports like DNS-over-TLS, HTTPS, and QUIC. These features are orders of magnitude more complex than the good old UDP and TCP, and this complexity provides fertile ground for bugs.
To make things even worse, "Who tests the testing tools?" Hardly anyone.
We developed a test suite for the testing tools and uncovered bugs which affected measurement results in various niche and not-so-niche corner cases.
In this presentation we summarize our findings and alert the audience to gotchas when benchmarking DNS software.
