NSD 4.13.0 is now available. The most prominent new feature of our authoritative #DNS server is support for AF_XDP sockets.
With zero-copy disabled, we see a 1.7x improvement in handled queries per second compared to UDP through the network stack. We expect the improvement to be higher with a driver that fully supports AF_XDP zero-copy mode.
Release notes:
