Well - let me describe how we like to do our benchmarking.

Ah, I see. But I have no explanation. I have tested with a Intel Xeon
CPU with 8 cores.

Hello Ciro,
Your server has 8 cores. I don't know if the Recursor benefits from
hyperthreading (would be good to know). If you run the Recursor with
threads=4 you have only 4 cores left for the clients. I got the best
result with 4 Recursor threads and two clients. But I think you can
improv

Hi Ciro,
Tried it quickly with dnsperf (http://nominum.com/measurement-tools/):
# echo -e "localhost.\tA" > datafile
# pdns_recursor --threads=4 --pdns-distributes-queries=no
# dnsperf -c2 -n 1000 -l 10 -d datafile

Hi!, could anybody achieve more than 100k QPS on a recursor while hitting
cache?.
I only run two tests so far and in both cases the ceiling was around 100k
QPS. The machine seems to be able to take more beating, maybe I just need
more clients or there's some kind of logic limit.
Any comments?.
