Currently I am looking for a web page speed test that can test the web page from multiple locations at the same time. The only one I can find online is https://performance.sucuri.net/. But it does not brings enough data.
Then I find this picture https://guozeyu.com/images/2017/cdn-9.png, which contains all the data I want.
I try to find the contact information of the author but failed. So I just wonder if anyone know on which site this performance result is generated?
