A kind reminder to please provide your feedback on the #XDP implementation we did for NSD, our authoritative #DNS server.
With zero-copy disabled, weI saw 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.
We're curious to hear about your experiences!
