The optimization of a website is also about testing the performance to determine what elements can be optimized to yield performance. With WP Speed of Light you can run several tests on the same page and open a comparison table. We've made an integration with WebPageTest API (free) to run detailed speed tests on various elements like:

• First loading time
• Second loading time
• First byte time
• Time to start rendering
• Element served from cache in %
• Elements compressed with Gzip in %
• Percent on compressed images

If the cache have been served using WP Speed of Light, you got a green symbol, if not it's grey, as simple as that! Furthermore, you can determine wether the desktop, tablet or mobile cache is served. JoomUnited cache checker also displays general information (apply to all websites): 

• Total page loading time
• Varnish server cache
• When the Varnish cache have been generated (current or previous request)
• Details of the loading time by element: Waiting browser reply, Redirect (if any), DNS resolution, Connect to server
• Details of the loading time by element: Content sending, Reveive, Unload time, Dom time, Load time
