hello, i've been trying to find the performance numbers for a CNR with, for example, minimum hw requirements. what i want to know is, for example, how many A-record QPS (queries-per-second) a CNR server would be able to handle. i know this could be tricky, but what i'm looking for is some kind of reference(at least). say my dns service should be able to handle a total of 50k QPS for both A-record and forwarded queries, how can i measure how many CNR servers (if load-balanced) are needed?

please advice.

c.
