Description
DNS Rex: Do you need an aggressive benchmarking tool?
I would like to present DNS Rex, an open source performance benchmark for DNS servers, with a focus on busy DNS caching resolvers. DNS Rex was created to address several known (and rumored) problems with existing DNS testing tools. Our goals included:
* reliable generation of high query rates,
* reproducibility of test results,
* ability to sustain any configurable cache hit ratio,
* support for long tests without reliance on trace replay,
* independence from a 3rd-party authoritative server,
* DNSSEC support.
DNS Rex has been successfully used for private tests, and is publicly available[1], but we have not promoted its wider use. Besides describing what DNS Rex can do today, I would like to gauge audience interest in continued development of the tool. Is there a genuine need for a better DNS benchmark? What missing features are the most important?
