About this tag
This quad9 tag archive covers discussion of Quad9 DNS performance, with a focus on encrypted DNS-over-HTTPS (DoH) versus plain DNS. The featured café Wi‑Fi test compares Quad9 with the network’s default resolver and reports that Quad9 over DoH averaged about 21.5 milliseconds, while plain Quad9 DNS averaged roughly 46.3 milliseconds in that session. The result is presented as a specific network observation, not proof that DoH is always faster. It also examines how persistent, well-routed connections can affect real-world lookup performance, challenging the assumption that encryption necessarily creates a meaningful slowdown.

    Cafe Wi‑Fi DNS Test: Quad9 DoH Matches Speed, Beats Plain DNS

    A café Wi-Fi test comparing the network’s default DNS, Quad9 over plain DNS, and Quad9 over DNS-over-HTTPS found encrypted Quad9 lookups averaging about 21.5 milliseconds, nearly matching the café resolver and beating plain Quad9 DNS at roughly 46.3 milliseconds in that session. That result does...
