​Network Performance Benchmarks

Before beginning a tuning exercise, it is important to have a good baseline measurement of your network performance. Usually in addition to getting an initial measurement of your specific application/workload's performance, it is a good idea to also use a standard network performance benchmark to verify that your network device is in a good state.

For single system optimization, netperf or iperf and NetPIPE are all solid open-source free tools that enable you to stress a connection and diagnose performance issues. Netperf is strong for both throughput and latency testing. NetPIPE is a latency-specific tool but can be compiled for any sort of environment.
