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.

JPerf features and specs

  • User-friendly Interface
    JPerf provides a graphical user interface, making it easier for users who are not comfortable with command line tools to perform network performance testing.
  • Cross-platform Compatibility
    JPerf is built on Java, which allows it to run on multiple operating systems including Windows, Linux, and macOS without modifications.
  • Network Performance Visualization
    JPerf offers graphical representations of network performance, such as throughput and jitter, making it easier to understand the results.
  • Integration with iPerf
    JPerf utilizes iPerf as the backend, benefiting from iPerf's robust network performance testing capabilities.
  • Customizable Testing Parameters
    Users can customize parameters like protocols, port numbers, and bandwidth, providing flexibility in performance testing.

Possible disadvantages of JPerf

  • Abandonware
    JPerf has not been actively maintained for several years, which means it may lack support for new features or bug fixes.
  • Limited Functionality Compared to CLI
    While the GUI is user-friendly, some advanced functionalities available in the iPerf command line version are not accessible in JPerf.
  • Dependency on Java
    As JPerf requires Java to run, users must ensure that Java is installed and correctly configured on their systems.
  • Potential Compatibility Issues
    Due to its lack of updates, JPerf may face compatibility issues with newer versions of operating systems or Java.

  • 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
