Those numbers are so low, it's anyone's guess where the bottleneck is.
58 qps works out to barely more than 5 million queries in the course of
a day, and I have aging old Sparc Ultra 2s, almost a decade old, that
can do way more than that. With your hardware specs, I think your
numbers should be much higher.
Why the bottleneck would affect authoritative queries/responses more
than recursive queries/responses, is another mystery, but one that may
become obvious when you get to the root of the problem.
