In order to know how our plugin impacts loading times we need to differentiate between frontend mode and editor mode.
Frontend Mode
There is no unnecessary code loading on the frontend for the features that you have not used in the backend. In frontend mode, we only load the CSS/JS files needed for the functionality you have activated.
Editor Mode
In editor mode, it is mandatory to load all CSS/JS files to be ready for use in the Elementor editor. If you have all the features of our plugin active, it may affect the loading time of the editor. In that case, you could reduce the active features or increase the WP_MEMORY_LIMIT.
