To test the performance gains from HTTP/2, the simplest way is to visualize the impact by using a web page which contains a large number of elements, such as images. Progress Kemp have provided a sample web page that displays an image made up of 1024 image ‘tiles’. Simply browse to the HTTP/2 and HTTP 1.1 Virtual Services to see the difference in performance. Ensure you use a HTTP/2-enabled browser, such as Chrome, when performing this test.
