[Unbound-users] Newbie's 48-hour stats

Hello.

Below are the stats from a 48-hour run of Unbound v1.4.12, which raises a few questions.

1. That request list depth of 39, is that excessive?

2. That average recursion time of 3 seconds seems high to me.  Is it?

3. Can I configure Unbound such that it times out prior to waiting 1024 seconds for
the expected data?  My thinking is that if the data doesn't arrive in, say, 60 seconds that it won't be arriving at all.

Thanks.
