On this page, you can minimize the size of various files such as HTML, CSS, and JavaScript files. You can freely activate any features that are needed.

However, in most cases, this arrangement does not have such a significant impact on overall website performance.

Unless your website has such large traffic as e-commerce, then this feature can have a real effect. Like reducing bandwidth usage or saving your hosting costs.

But sometimes, minimizing file sizes can also potentially cause unexpected risks.

Step 5 – Lazy Load Media

Images are often one of the second heaviest items on web pages after videos. The loading process is longer than the text. So, to get around this, many websites use the help of the lazy loading plugin.

Instead of loading all the images at once, the lazy loading feature will only display the image when the user sees it. In this way, loading your website can run faster. 

Fortunately, the WP Rocket plugin comes with a default lazy loading feature. The way to activate it is to open the Lazy Load settings like the picture above, then you can choose which features you want to activate. Here is a full explanation of each feature:

Usually, this Advanced Rules setting is only needed by developers with complex website systems.

Step 8 – Database Settings
