It used to be the case that I could flush the unbound cache and then resolve a
name immediately. Now there is a long delay before I start to get results. It
is especially bad on Fedora 15 running in VirtualBox on OS X Lion, but I'm also
seeing it slow down on Fedora 15 at EC2. I updated root.hints, but that didn't
seem to help. I can't make much sense of the debugging logging output. A couple
weeks ago, flushing cache or restarting, you might notice a light delay on the
first lookup, but now it takes a few minutes to get results other than timeouts.
