Think about it, if you compress your website files, will the speed increase? The answer is yes. https://support.cloudflare.com/hc/en-us/articles/236166048-Caching-Static-HTML-with-WordPress-WooCommerce

Last night I deployed SSL to my website, but after installing wordpress this morning, SSL made my website completely different. The reason is that it affects the website loading css and js files. My first thought was to modify the permalink in the background, as shown in the figure below. But it didn't work, and I couldn't access in admin anymore, damn it! Then, if there are too many login redirects in the background, just add the following code at the beginning of wp-config.php in the root of the website. Then this problem is solved perfectly!
