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.

  • XML API Documentation: From Zero to Production in 10 Minutes

    We would really prefer to use a somewhat generic pre-made tool for this (such as DocFX) compared to rolling our own solution. We can roll our own solution... But would prefer not to so that we can minimize development and maintenance overhead. Source: over 4 years ago
