​Network Performance Benchmarks

Before beginning any tuning exercise, you should have a good baseline measurement of your network performance. Also, in addition to the initial assessment of your specific application/workload performance, you should use standard network performance micro-benchmarks to verify that the network device is in a good state.

To benchmark interface speeds of 25 Gbps and higher, it is common to require that multiple traffic threads utilize the connection. ​iperf2 and ​iperf3 provide examples of common micro-benchmarks that are known to work well.
