Got wind of this yesterday - https://www.fastorslow.com/ for testing page speed loading titimes. Launched by Wordfence.com they have this to say about the tool. Fast or Slow is the first and only free website speed test in the world to test your site simultaneously, from multiple geographic locations, and give you real-world performance results based on actual browser simulations. Fast or Slow doesn’t just give you the network or ‘ping’ speed of your site. It actually tells you how fast your site is from initial DNS lookup to how long it takes your HTML to render in the browser. And it does that from 13 locations, allowing you to drill down into each location for more detail. Well worth a look.
