Render blocking resourses problem

A lot of these refer to minified/merged files

As you have http2 enabled (you can check this here: https://tools.keycdn.com/http2-test) I would not enable merging/minification.

When loading a website from an HTTP1.1 server, A single request is processed at a single time period. therefore, the browser will first download the CSS, then another CSS, then another JS, then an image, and then the page will be rendered. This happens one after another, until all assets are loaded on the page. If you check a waterfall chart for this type of website loading, you will see that one request ends, and another one begins.

That’s why the conventional wisdom is that merging all of these requests into a single larger request is true, and will speed up the loading time of your website. And this is absolutely true. A single HTTP request on an HTTP 1.1 based server will always load quicker then multiple, as there is no waiting period.

With HTTP 2, All requests are loaded simultaneously. There is no waiting process, and there are the same number of connections for the number of assets being requested. Therefore, merging and minifying will simply create a larger file, taking a longer time to upload and download, leading to a longer render process for the website. By keeping all of your individual files unmerged and minified on WordPress, they can all load at the same time, and each upload and download is for a smaller file, resulting in a quicker loading time.
