Possible disadvantages of Flent

  • Complexity for Beginners
    The comprehensive nature of Flent can be overwhelming for beginners or those unfamiliar with network testing, as it requires some technical knowledge to set up and interpret results.
  • Limited GUI Support
    While Flent does offer a graphical user interface, the primary interaction with the tool is through command-line, which may not be as user-friendly for some users.
  • Performance Dependent on External Tools
    Flent largely relies on other network testing tools for its operations, which means any limitations of these tools can affect the overall performance and results of Flent tests.
  • Resource Intensive
    Running comprehensive network tests using Flent can be resource-intensive, requiring significant processing power and memory, especially for detailed or prolonged tests.

netperf features and specs

  • Comprehensive Performance Testing
    Netperf is a versatile benchmarking tool that provides a robust suite of tests for evaluating various aspects of network performance, such as throughput, latency, and transaction rates. This allows users to gain a detailed understanding of network performance under different conditions.
  • Wide Protocol Support
    The tool supports a range of protocols including TCP, UDP, and SCTP, as well as a variety of test configurations. This flexibility allows users to tailor the tests to match specific network conditions and requirements.

Possible disadvantages of netperf

  • Command-Line Interface
    Netperf primarily operates through a command-line interface, which can be complex and unintuitive for users who prefer graphical user interfaces or are not experienced with command-line operations.
  • Steep Learning Curve
    New users may find it challenging to properly use Netperf due to its wide array of options and configurations. Understanding all the nuances of the tool to perform effective tests can require a significant learning effort.
  • Limited Documentation
    While there is documentation available, it may not be as extensive or as user-friendly as needed, which can make it hard for beginners to quickly find the information they need to execute specific tests.
  • Specialized Use Case
    Netperf is highly specialized for network performance testing, which limits its utility outside of networking contexts. Users seeking a tool with broader capabilities beyond network measurement might need to look elsewhere.

  • Most accurate internet speed test.
    You should try Flent from the BufferBloat project. Source: almost 2 years ago
  • Tools for measuring Network convergence, delay and packet loss
    Flent (Flexible Network Tester) is a powerful network testing utility that aims to simplify the process of gathering and analyzing network performance metrics. Built on top of other open-source tools like Netperf, Iperf, and Ping, Flent automates the process of running multiple tests simultaneously and aggregates the results into comprehensive, easy-to-interpret graphs.

  • Help eliminating buffer bloat on connection speeds over 1gbps
    Hmm... It does not take much packet loss to slow tcp down at that rate. A better test would run longer than waveform, like the flent.org tcp_ndown test. Source: over 2 years ago
  • Loaded latency with fast.com?
    Also most of our web based tests do not last long enough to show the full extent of the problem. Waveform, while pretty good, doesn't test up and down simultaneously, nor does it last long enough. I've put out a few measurements here or there about what Starlink looks like over time, such as most recently, over here: https://github.com/mininet/mininet/issues/1119 - long term spikes for "Working latency" on...

  • 6.6 is out
    Install Flent. See the bottom of https://flent.org/ for instructions. Source: over 3 years ago
