|Page Rendering||When someone views a web page, the browser builds the page by processing each line of code in order. This is known as page rendering.|
HTTP/2 is currently supported by 95.6% of internet browsers. As of 6 January 2022, HTTP/2 is used by 46.9% of all websites online, though you can see from the graph below that this figure is significantly higher among the most popular websites on the internet.
Be sure to run performance tests before and after combining files so you know how page loading times have been affected. You can do this using GTmetrix, Google PageSpeed Insights and the Pingdom Website Speed Test.
I have used Autoptimize on many WordPress websites as it always improves page loading times.
