Possible disadvantages of iPerf3

  • Command-Line Interface
    iPerf3 primarily operates through the command line, which might be daunting for users unfamiliar with command-line tools.
  • Limited Graphical Visualization
    It lacks native graphical user interface (GUI) options, requiring external tools for visualization of results.
  • Single-Threaded
    iPerf3 itself is single-threaded, which may limit performance testing on multi-core systems unless multiple instances are used.
  • UDP Test Limitations
    While iPerf3 can test UDP performance, the results can sometimes be less accurate compared to TCP testing due to UDP's nature.
  • No Native Secure Connections
    iPerf3 doesn't natively support encrypted connections, which may be a concern when testing over untrusted networks.

  • WAN circuit testing
    I think such a tool is fairly straightforward to develop with iperf 2 as the underlying src/sink. The man page has new features including start times & permit keys. Active, low duty-cycle, low impact telemetry has been a goal. The idea is that someone else would develop a web app and host public servers. As an iperf 2 maintainer, I'm trying to remain arm's length from such products but I do think the industry... Source: over 2 years ago
  • WAN circuit testing
    Iperf 2 can help and has many new tests including one way delay, low duty cycle burst, tcp bouncback, etc. More on the man page. OWD does required clock sync. Source: over 2 years ago
  • Is iPerf test an officially approved RFC 2544 test?
    A bit of a tangent, but there are a lot of new features in iperf 2, much are around latency or one way delay (OWD). Many times these days it's latency that affects the quality of experience to end users. Source: about 3 years ago
