What does HTTP/3 change?

HTTP/3 moves communication to QUIC, reducing part of the latency known from traditional connection setup.

When will users notice it?

Most often on mobile traffic, unstable links and pages loading many resources.

The application still matters

HTTP/3 does not replace cache, image optimization, PHP-FPM, OPcache and a healthy database, but it complements the performance stack.
