> As a blocker for DNSSEC ... people made arguments about HTTPS overhead back in the day too. They did, and then we spent an enormous amount of time to shave off a few round trip times in TLS 1.3 and QUIC. So I'm not sure this is as strong an argument as you seem to think it is. > DoH also introduces latency, yet people aren't worried about that being a deal killer. Actually, it really depends. It can actually be faster. Here are Mozilla's numbers from when we first rolled out DoH. https://blog.mozilla.org/futurereleases/2019/04/02/dns-over-... And here are some measurements from Hounsel et…

"We discovered that current DNS clients do not utilize part of the DNS Internet Standard that could improve client performance and user experience. Unfortunately, the three public recursors we measured violate the standard [27] by not supporting queries with more than one question (QDCOUNT > 1). Cloudflare and…

Here's a whitepaper that did some benchmarks and a detailed analysis on it. Was posted on hn a few days ago. https://arxiv.org/abs/1907.08089 They test various network conditions with some results showing DoH and DoT loading webpages faster than udp dns (due to tcp timing out faster than udp on lossy connections )
