I don't believe this is specifically a FreeBSD UDP performance issue.
Using NSD as the nameserver and fast core-2 duos, FreeBSD was able to
old 140k queries/sec while linux (on the same machine) ran 90k queries
per second.  This was using two server threads.  I believe the numbers
were 120k and 80k for one server thread.

But: the whole reason I'm testing NSD for a client is because BIND has
huge performance bottlenecks with large zones (bind reportedly takes
20 minutes from when it run to when it's ready to serve the first
query).
