What ways are there to measure response times for DNS queries? dig does
it for each query.

The performance and monitoring tools I've seen so far seem to track
query types, targets and sources, or tell you whether servers are
answering at all, but I'm after something that we can run over quite a
long time that will show us things like the minimum, average, maximum
average response time, average last five minutes, that sort of thing.

Something like dsc, which sniffs an ethernet interface, would be ideal.

Any ideas?

Regards, K.
