Is there anything that could explain this:
Here we have:
- The same hardware (Intel NUC 7i5BNH)
- The same network (network cable and router) and the same ISP
- The same operating system (Windows 10 Pro 10.0.19044 Build 19044)
- The same network speed testing tool (fast.com) and the same destination test server
- The same set of applications running in background
- The same timeframe (both tests run one after another, with 30 seconds separation)
- And two different browsers (Google Chrome 101.0.4951.67 and Microsoft Edge 101.0.1210.53)
And we have network speed reported by two browsers that differs nearly eight times.
This is not a separate situation. The same tests were run (and the same results were received) a couple of times for the following next hour.
To make things even more weird (at least to me) very similar tests were performed in the mean time (again with 30 seconds separation between each test) on another PC. The testing framework was exactly the same (again same network, ISP, operating system, timeframe, testing tool, server and the same set of two browsers), but only run on another PC.
And in this case both browsers has reported nearly the same results:
Is there any reasoning that can explain that a single browser reports a way different results in a repeatable conditions that another browser on the same computer and all other browsers on all other PCs connected to the same network?
