We re-run the tests with concur.
The result were better:
Test with rule drop:
no noticeable change, around 650kqps, guess this is network or stack limit
Test with rule REFUSED:
dnsdist from rpm: ~450 Kqps
Test with answer from cache:
1 dnsdist from rpm 12 listeners: ~130 kqps
3 dnsdist from rpm 6 listeners each: ~370kqps
1 dnsdist-concur 12 listeners ~170 kqps
1 dnsdist-concur 20 listeners ~170 kqps
3 dnsdist-concur 6 listeners each ~450 kqps
Hope this help.
