DNS over HTTPS is actually a lot slower to resolve than traditional UDP DNS.

• gsich 8y ago
  Yes, but only because of TCP and TLS connection overhead. Once the connection is established, response time is similar to UDP.

    Does the connection get reused?
    • cbsmith 8y ago
      Yes.
      • gsich 8y ago
        Not for long.

          If the browser is controlling the resolver in question, there's no reason not to hold long-running connections, or reconnecting on disconnect.
