When I try to check speed on SpeedTest.net, it says selecting best server based on pings. Does it calculate the speed using the ping request and reply packets if so how?
1 Answer
From the speedtest.net support page,
The ping is the reaction time of your connection–how fast you get a response after you've sent out a request. A fast ping means a more responsive connection, especially in applications where timing is everything (like video games). Ping is measured in milliseconds (ms).
There are other frequently asked questions with answer in their support section, including How does Speedtest.net know where I am?. However, these are very broad descriptions. More on ping
can be found by reading about the utility, as well as the ICMP.

This doesn't actually answer the question. It explains what ping is but it doesn't explain that ping isn't used to calculate speed.– DavidPostill ♦Apr 6, 2016 at 20:57
