Network testing tools such as netperf can perform latency tests plus throughput tests and more. In netperf, the TCP_RR and UDP_RR (RR=request-response) tests report round-trip latency. With the -o flag,  output metrics can be customized to display the exact information. Here’s an example of using the test-specific -o flag so netperf outputs several latency statistics: Google has lots of practical experience in latency benchmarking and as per blog  using-netperf-and-ping-to-me
