How to Measure Network Performance

Networks, Network Performance, and You

Key Network Performance Metrics to Measure

How do you know the state of your network?

  • iPerf
  • iPerf has to be run on both a device and a server, and it measures throughput between them.
  • Speedtest by Ookla
  • Speedtest will show you your observed throughput between Ookla’s servers and your device. This is the bandwidth your device actually sees, so it’s net of all possible loss and jitter your network may have.
  • Packet Loss Test
  • Packetlosstest.com tells you your device’s packet loss, latency, and jitter from within your web browser. If your service isn’t accessible from a web browser, you can still use it to see a part of your network, even if not the whole of it. And again, this is between Packetlosstest’s servers and your device.
  • MTR
  • MTR is a wonderful tool which shows the network path and status between your device and desired service, but it’s very technically oriented and lacks the sort of user interface the other tools offer.
  • Netperf
  • An oldie-but-a-goodie. Netperf consists of a client and server, you run the client on your device, usually a computer, and the server on the server you’re trying to talk to. It takes some expertise to use this tool, but it’s worth the effort.
