Hi,
I measured the response performance as "Queries sent" with the queryperf
program for 30s and for 6 times.
queryperf asked various host names randomly generated.
queryperf and named run on the same server.
CPU: 2x Pentium III/Pentium III Xeon/Celeron (601.37-MHz 686-class CPU)

I've seen with libthr the performance increase significatly according with
Marcelo.
