Divi Nitro is a Divi theme specific speed optimisation framework.
Divi Nitro is designed to boost your page loading speed which helps improve SEO and most importantly the visitor’s user experience.
What are deferred images?
A deferred image is downloaded after the initial page load (after the scripts).
How does it make my Divi site faster?
Images are one of the major factors in slowing down the page load time. Lots of images equals slow loading site. You may be able to optimise your images but cannot get away from the fact that you have lots on your page. This is where Divi Nitro comes in. Divi Nitro uses deferring images to load the images AFTER the initial page load. It then loads the images after that from the top down.
Your site visitor sees the page load in a matter of seconds. As they are reading the images are loaded in the background without them knowing, so when they scroll down the images are loaded and looking great.
As you can see in the above example by deferring images it reduced the load time from 5.20 seconds down to 1.18 seconds.
Isn’t this lazy loading?
Well yes and no, lazy load is a more complicated way of deferring images. It observes, monitors and reacts to the scroll position – then it defers the images.
This way the image will ONLY load when the user scrolls to the position of the image. Lazy load can cause performance issues, is not a viable solution for one page websites and is not ideal for mobile performance.
See the power of Divi Nitro using the Divi modules that have images. This example has multiple high res images that would cause the page to load slow. They are using the Divi image module. Notice how quick the page loads even with loads of images.
Script Minification & Combination
Why minify and combine scripts?
Simple, minify means to make smaller. The smaller the css & js the quicker the page will load.
Why use Divi Nitro and not other plugins out there?
Take control of what scripts get minified with Divi Nitro. You can see what scripts have been enqueued and choose which files you want to minify and combine.
Are two files not combining correctly? Don’t worry, just put one in another queue to be compressed and avoid script errors on the front end.
Divi Nitro only minifies:
1) Enqueued scripts (proper way to add scripts in WordPress – Divi and other well-developed plugins would add the scripts this way)
2) Scripts on your server and not on another server such as google CDN (this is impossible as you have no control over these files).
