I bought GeneratePress because it was listed as one of the 10 fastest themes in a test, and it hasn’t disappointed. With some tweaking I’ve gotten my PageSpeed score to 93 for mobile and 99 for desktop, and all green on all the metrics except Largest Contentful Paint on mobile.
So there are still some tweaks I’d like to do. Some of the css files each add around 150 milliseconds to my renderblocking time, and I’d like to include them in my “custom css” file instead of loading them separately (featured-images.min for example). But, neither wp_deregister_style nor wp_dequeue_style work to stop them from being loaded. I use these wordpress functions to remove css loads from plugins just fine, but not the theme.
Ideas?
