iperf features and specs

  • Cross-Platform Compatibility
    iperf is compatible with a variety of operating systems including Windows, Linux, and macOS, making it a versatile tool for network performance testing across different environments.
  • Comprehensive Performance Metrics
    Provides detailed metrics such as bandwidth, jitter, and packet loss, which are essential for in-depth network analysis and troubleshooting.
  • Client-Server Model
    Utilizes a client-server model that allows for measuring the maximum TCP and UDP bandwidth between two endpoints, making it suitable for both local and remote testing.
  • Open Source
    Being open-source, iperf allows users to review, modify, and contribute to the codebase, ensuring transparency and fostering community involvement.
  • Customizable Test Parameters
    Allows users to customize tests with various parameters such as port number, buffer size, and test duration, offering flexibility to perform targeted network evaluations.

Possible disadvantages of iperf

  • Complexity for Beginners
    The command-line interface and numerous parameters might be overwhelming for beginners who are not familiar with network testing tools.
  • Limited Graphical Interface
    While powerful in functionality, iperf lacks a native graphical user interface, which could be a disadvantage for users who prefer visual tools over command-line utilities.
  • Resource Consumption
    iperf can consume substantial network resources and CPU power during testing, potentially affecting other applications running on the same network or device.
  • Manual Deployment Required
    Users need to manually deploy iperf on both client and server machines, which may be cumbersome for those looking for out-of-the-box network testing solutions.
  • Security Considerations
    Running iperf in server mode might expose a system to network attacks if not secured properly, necessitating careful consideration of security measures.

  • Microsoft: Don't Use Iperf3 on Windows
    Just some clarification: IPerf 2 is different from the iperf3 found at https://github.com/esnet/iperf. - Source: Hacker News / about 1 year ago
  • Yet Another Bench Script (YABS): evaluate Linux server performance with this simple Bash script and utility
    Network - network throughput (both incoming and outgoing) is tested using iperf3 on several geographically diverse public iperf servers. Source: over 2 years ago
  • Speed testing Visible with a modem
    File transfer using iperf3 over Tailscale. I noticed that the bandwidth to my home computer (on a 500/500 fiber connection) was higher than with speedtest.net. For the first few days I was getting downloads and uploads of 28Mbps (+/- std dev of 6Mbps) and 150ms latency (+/- 35ms). After somewhere around 100GB total transfer (maybe half of that over Tailscale), it is now downloading and uploading at 10Mbps (+/-... Source: about 3 years ago
  • FTP upload speed isn't great
    I can add to this. I have two mini self contained projects to create multiarch static bins of mtr and iperf3 for general usage. Source: almost 4 years ago
