Assuming:
- the numbers you gave are queries per second
- your v880 has 1.5GHz Ultra sparc III CPU (or similar)

and considering:
- BIND's atomic locking performs better on some platform than others
(my experience was on x86 vs ppc)
- query per second numbers on

I'd say you're probably cpu bound and there's nothing much you can do
about it. You already disabled logging, right? This is just a rough
estimate though, YMMV. If you have a 2 or 4-way x86 server you can try
it and see if it performs better.
