Testing DoH and DoT servers, compliance and performance

Of course, encrypting DNS is necessary for privacy and security, like for every other Internet protocol. That's why DoT and DoH deployment is very important, so that users could safely go to a resolver they trust. Now, it is time to assert the technical compliance and performance of these trusted resolvers. We will talk about the things that could and should be tested against DoT and DoH servers and how to implement it. We will then discuss performance measurements, specially with the opportunities brought by parallelism (both in DoT and DoH) and the challenges they create for measurements. This talk will be inspired by the development of a tool which is, at this stage, in a very alpha state.
