With djbdns, the default dnscache logs include statistics on cache
effectiveness. It's easy to measure how heavily loaded your cache is.
See http://cr.yp.to/djbdns/faq/cachex.html#cachemotion.

That's absurd. Users are much happier with dnscache, which stays within
the memory limit and continues providing reasonable performance even
under very heavy loads.

You didn't manage to take down email at sites running qmail. We
continued delivering to non-AOL sites without trouble.
