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.
As for the dropping of UPDATE queries, which is configurable and off by
default, it was a request from one our users. I'm unsure what the exact
reason was/is, but it's likely that they got a lot of queries from
badly behaving clients. By not answering at all, the client is probably
tricked into thinking the server is unavailable resulting in it giving
up.
