Today, we released version 4.3.0 of the authoritative DNS nameserver NSD.
This release adds CPU affinity. By pinning a server process to a specific CPU, having a separate network card also for that CPU, and an interface address also for that server process, the throughput is increased. This increases performance of the nameserver.
Sparse TSIG signing support is removed, to comply with the latest TSIG standard update draft.
There is a feature to drop update queries, with opcode UPDATE, with nsd.conf option drop-updates.
You can get source packages of this version from the downloads page.
