 Thanks to recent Linux kernel capabilities, namely eXpress Data Path and AF_XDP
-address family, Knot DNS offers a high-performance DNS over UDP packet processing
-mode. The basic idea is to filter DNS messages close to the network device and
-effectively forward them to the nameserver without touching the network stack
-of the operating system. Other messages (including DNS over TCP) are processed
-as usual.

-If :ref:`xdp_listen` is configured, the server creates
-additional XDP workers, listening on specified interface(s) and port(s) for DNS
-over UDP queries. Each XDP worker handles one RX and TX network queue pair.
