Oh, those numbers are over 11 thousand queries per second for the
recursor, and over 7 thousand qps for the auth-only. The numbers
behind them are the standard deviations obtained from running ten
consecutive tests, and show that there was very little variation in
I'm suspecting some differences in code-paths between the two, that
can be the cause for the differences in qps performance. It would be
great if someone knew details on this.
