Possible disadvantages of Fast.com

  • Limited Metrics
    Fast.com primarily focuses on download speed and does not provide as comprehensive a range of metrics as some other speed test websites, such as upload speed, latency, and jitter.
  • No Server Selection
    Users cannot choose which server to run the speed test against, which can sometimes result in less accurate measurements for specific network conditions.
  • No Historical Data
    Fast.com does not offer features to save or track historical speed test results, limiting users' ability to monitor their internet performance over time.
  • Lack of Customization
    There are no options to customize the test parameters, such as test duration or concurrency levels, which might be relevant for more advanced users.
  • Geared for Streaming
    Since Fast.com is tailored for Netflix streaming, it may not fully represent other usage scenarios, such as gaming or file downloads, which require different network performances.

speedtest-cli features and specs

    Speedtest-cli is open-source, meaning the source code is freely available for anyone to inspect, modify, and enhance.

Possible disadvantages of speedtest-cli

  • Requires Terminal Knowledge
    Users need to be familiar with the command line interface, which might be a barrier for those who are accustomed to graphical user interfaces.
  • No Graphical Output
    Lacks a visual representation of the speed test results, which can be a disadvantage for users who prefer graphical data.
  • Limited Server Selection
    Automated server selection might not always choose the best server for testing, potentially affecting the accuracy of results.
  • Dependencies
    Speedtest-cli relies on Python and the 'pip' package manager, which may require additional setup steps for some users.
  • Feature Limitations
    Not all features of the web-based Speedtest service (like detailed historical data) are available in the CLI version.
