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? [1] http://rex.measurement-factory.com/


A presentation about DNS Rex, a performance testing tool for busy DNS caching resolvers. Why was it created? What can it do? Where do we go from here?
