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.

  • I Built a Fast.com for LLMs: Introducing iamspeed.dev
    That is exactly how fast.com works for internet speed tests. You open it, it runs, you see a number. Done. - Source: dev.to / 2 months ago
  • Streaming the 2026 Winter Olympics: A Developer's Guide to Live Sports IPTV
    Pro tip: Run a speed test immediately before the event. Don't trust your "up to 100 Mbps" ISP claim. Use fast.com or speedtest.net to get real numbers. - Source: dev.to / 6 months ago
  • Downdetector, Speedtest sold to IT service provider Accenture in $1.2B deal
    Speedtest has always seemed incredibly sketchy to me, I donโ€™t know if others share this sentiment. https://fast.com completed the test faster than speedtest loads the site. - Source: Hacker News / 6 months ago

    Is this for remote access VPN? If so, what kind of bandwidth are you seeing on a speed test site like fast.com (with the VPN off) compared to the VPN bandwidth you're experiencing? Source: over 2 years ago

  • I Love FreeBSD
    What I really want is the Windows tool for that. Can't call it equivalent, because clunsy is way superior. https://jagt.github.io/clumsy/index.html. - Source: Hacker News / 5 months ago
  • YouTube's new anti-adblock measures
    I imagine there are tools that will artificially slow down requests. The lazy way would be to VPN somewhere as far away as possible and throttle your bandwidth. That would get you 250ms of round trip latency for free. In Antarctica we had up to 3000ms on a bad day. This app looks fun: https://jagt.github.io/clumsy/index.html (randomly interferes with your packets). - Source: Hacker News / about 1 year ago
  • how do i simulate clients with high ping?
    I have used little program called clumsy: https://jagt.github.io/clumsy/index.html. Source: about 3 years ago
  • wireguard vs tailscale for latency
    You could install 100ms of lag using a tool like clumsy to test it out: https://jagt.github.io/clumsy/index.html. Source: over 3 years ago
  • Is there (I suspect not, could there easily be) a way to spoof some additional latency, in order to have a fair match with normally uneven pings
    I Google for โ€žhow to emulate network latencyโ€ and found this on Stack Overflow. Source: almost 4 years ago
