bind9 will be slower to respond in the average case right now.  We are
more concerned about standards compliance, with an eye to
optimization, than optimizations right now.  However, we are working
to speed things up.

Locks are pretty fast -- a slow PII can do well over one million/sec.
However, locks do slow things down a bit.

Also, bind9 won't help on two processors (much) unless you're doing
DNSSEC.
