Response Rate Benchmark

The testing infrastructure consists of two physical servers directly interconnected via 10GbE. One server replays prepared DNS queries at various rates to the second server, which runs the name server software under test. The corresponding responses are monitored on the network stack to eliminated various network issues. The tools used to send the queries are tcpreplay and netmap.
