Use adns instead. http://www.chiark.greenend.org.uk/~ian/adns/ >I'm particularly perplexed that a K6-200 system I had was cpu bound >running named and achieved ~200 resolves/sec; my spiffy new 1100 MHz >K7 is struggling to double it. You should be able to acheive that perfomance with one process running adns. You should be able to do much better if you add a cache (even quite a small one), since IP addresses in web logs are quite repetitive.
