See http://marc.theaimsgroup.com/?l=bind-users&m=101081439312759&w=2 for
measurements I've made on the resolution capacity of BIND 8 and
dnscache. I've been able to resolve close to 1000 queries/sec - purely
resolving records *not* in it's authority, with no cache (fresh start of
the server before testing).
BIND 9, on the other hand, performs very poorly as a resolver. I've
tested it on Solaris and Linux, threaded and not threaded, sun compiler
and gcc, sparc and intel on Solaris - and BIND 9 never does well. I
usually get around 150 queries/sec for resolution in tests (sometimes
much, much worse).
I welcome you to compile queryperf in the BIND 9 contrib directory and
see what kind of results you get.
Oh, and I'm not getting suckered into trying to respond to the address
