We recently put a stock Fedora Core 6 and a stock FreeBSD 6.2 on the same
HW (HP ProLiant DL320 G5 Dual Core Xeons w/ 16GB RAM) and running BIND
9.4.0 and a well known ccTLD zone that we slammed a query stream to. On a
single threaded BIND, there was a 20% advantage to Linux, on a multi
threaded build, Linux trounced FreeBSD (39k to 89k queries/sec)
There's also been other analysis done by Marcelo Amarai @ Registro.br that
was posted to freebsd-net back last September.

I have a couple of dual Woodcrests running back-to-back over multiple 10GigE
cards that I'd like to do performance testing with. Did you use the same
testing methodology as Marcelo? If not can you go into more detail on your
setup and how to reproduce?
BIND9 includes a tool called "queryperf" that can be used to generate DNS
query workloads against a DNS server and characterize the results. You'll
need to provide zone(s) and a list of queries to perform. It's not imported
in our contrib tree, but can be found in the port.
