Hi Joe.

I would rank our installation as large. Not large like eBay but larger
than average to be sure. I can testify that the performance of
PowerDNS with the BIND backend, when compared to BIND, at least in our
case, is astounding. When I replaced one particular BIND 9 server with
a PowerDNS server, the query counts on the mrtg graph nearly tripled.
It is simply faster at answering queries. There are some feature
limitations to PowerDNS, and I'm still working on a couple of issues
with it, but they all seem like things that can be worked out. Unlike
BIND, which for whatever reason (perhaps the relatively severe load we
place on our nameservers) just can't stay running and has to be
periodically restarted and occasionally rebooted, and exhibits other
inexplicable problems.

The day we installed our first PowerDNS server was the day we finally
rested easy with regard to our nameservers. And the built-in web-based
reporting tool is surprisingly useful.
