iPerf

iPerf is a network bandwidth throughput testing software. This test profile is used for automated testing of an iperf client and requires you have access to an iperf server.

This test profile automates the testing of a iperf3 client. Ensure you have a suitable iPerf server running on your network prior to running this test.

To run this test with the Phoronix Test Suite, the basic command is: phoronix-test-suite benchmark iperf.

Performance Metrics

Analyze Test Configuration:

iPerf 3.14

Server Address: localhost - Server Port: 5201 - Duration: 10 Seconds - Test: UDP - Parallel: 1

OpenBenchmarking.org metrics for this test profile configuration based on 102 public results since 22 July 2023 with the latest data as of 13 November 2024.

Below is an overview of the generalized performance for components where there is sufficient statistically significant data based upon user-uploaded results. It is important to keep in mind particularly in the Linux/open-source space there can be vastly different OS configurations, with this overview intended to offer just general guidance as to the performance expectations.

Based on OpenBenchmarking.org data, the selected test / test configuration (iPerf 3.14 - Server Address: localhost - Server Port: 5201 - Duration: 10 Seconds - Test: UDP - Parallel: 1) has an average run-time of 2 minutes. By default this test profile is set to run at least 3 times but may increase if the standard deviation exceeds pre-defined defaults or other calculations deem additional runs necessary for greater statistical accuracy of the result.
