Threading does help which is why you are using as many cores as you are. There may be a bottleneck that needs to be addressed that keeps the system from scaling linearly. In that case, a second front-end pointed at the same backend database may give you 2X the number of queries/sec if the choke point is in the PDNS frontend and not the DB backend.
