I couldn´t let this pass without posting something worthwhile for me 3,000th milestone on this amazing community. So, giving these past few months I´ve been research and learning a hell lot about how to optimize a WordPress-based websites page loading speed and, especially, how to do it WITHOUT plugins, I would like to share with you guys some stuff I found around the internet that has helped me with this.
Bear in mind, I don´t have a background in coding, programming, or even web development. I am, however, persistent and like to research a lot. So, before implementing any of these codes on any of your sites, be sure to backup everything and test.
These codes are meant to help to optimize any WordPress-based site by editing and manually adding some codes to the HTACCESS, function.php, and wp-config.php files. So, these codes are just for Apache servers.
I hope you can get some value out of this, cheers!!

Some of the code requires some editing, meaning, you´ll need to add your site´s domain or the image's actual width and height. Other than that, I think all the codes are self-explanatory.
I will also share with you guys on the first post my own personal list of my favorite resources build around WordPress Speed/Performance Optimization.
And, as always, cheers and stay safe!!
