I find fast.com massively overestimates my speeds. Interestingly, if you hide the tab running their speedtest you get even higher speeds.

- dspillett 3y ago> I find fast.com massively overestimates my speeds. I find fast.com more accurate than most, going by the throughput I see to/from other resources, particularly for upstream rates (which some, including Cloudflair, seem to significantly under-measure). Of course this may vary depending on line type (FTTC, “up to 67Mbit down n& 17 up”, generally seeing more like 50/12) and location (due to differences in local network conditions and peering between you & the speedtest) to I'm not surprised to hear you see the results quite different to those I experience. > if you hide the tab running their speedtest you get even higher speeds I suspect this is due to your browser throttling CPU use and timer granularity for background or occluded tabs⁰ reducing the accuracy of the readings, if the code isn't working to mitigate the effect of these throttles on the calculations. -- [0] refs: https://blog.chromium.org/2020/11/tab-throttling-and-more-performance.html https://blog.chromium.org/2020/11/tab-throttling-and-more-pe..., https://www.reddit.com/r/incremental_games/comments/jefviz/fyi_how_to_disable_timer_throttling_on_google/ https://www.reddit.com/r/incremental_games/comments/jefviz/f..., and many more
