Yes, nice stats, especially the latency off course, from what i have
seen pdns answers queries faster than bind.
Btw: If you run a recursive/caching-only nameserver you don't really
need to put the pdns_daemon in front of the recursor as it doesn't
really make a difference in the time thats needed to access its cache.
So you can just try and make the recursor listen to your 'outside'
IP-Address instead of just 127.0.0.1.

I have 10 pdns_recursor processes that are up and running since 3.1.4
came out on November 13th and as far as i know there is not one report
of single crashed 3.1.4 recursor so far, so its pretty much the 'gold
edition' for me.
I have those 10 processes on 5 machines running behind a redundant
loadbalancer setup and just last Sunday i had a sustained peak usage
of 9950 queries/second.

The recursor also gives some nice statistics print, here is one process:
stats: 1078297759 questions, 1995041 cache entries, 16818 negative entries, 77% 
cache hits
stats: throttle map: 5060, ns speeds: 13533
stats: outpacket/query ratio 33%, 10% throttled, 0 no-delegation drops
stats: 49371 outgoing tcp connections, 36 queries running, 21638732 outgoing 
timeouts

ok enough bragging ;)

 It appears we really fixed the proverbial last bug in the Recursor.

 On 5 machines? Anybody who can top this? The highest number we've seen
 intesting was 8 qps on a very large Sun machine, but that was testing
 and not production.

How does one generate these stats messages?

Mark.

The recursor outputs them once every 30 minutes, or whenever you send a
SIGUSR1. 

The authoritative server has a built-in webserver that can be queried.

Good luck!
