You have noticed that TestMySite, the tool of Google, shows load time higher than Pingstool and Gtmatrix.
The reason is that TestmySite checks your site with Moto G4 device within a 3G network. It means your site is not checked within a 1Gps connection speed as it is the case with tools.pingdom.com.
Don’t believe it?
If you have 3G, check your site with it and keep a stop watch. When you open the URL, run the watch, and once it is loaded fully, stop it. You will be amazed.
Users also use 3G or 4G, not 1Gbps. Till 2020, people will have 3G like speed. That’s was the main reason to develop such a tool.
Pingdom shows the URL is loaded in 90ms, but TestmySite shows 2 seconds.
Moreover, the estimated visitors lose is based on the Google Research that you can read here
