Generic reasons for recursive performance not to peg CPU?

Howdy,
Without going into too much detail, doing some performance testing and
am seeing a weird result. On the same systems authoritative queries will
happily peg the CPU. However when running recursive queries (with a
small zone, all data cached before testing) the CPU never gets above
80%. The disk is nearly inactive on both systems, and there is no
swapping. Using BIND 9.9.4.
Is there perhaps something obvious I'm overlooking here? Any suggestions
are welcome.
Doug
