How does the 'Fast Loading' option work?
The Fast Loading option is one of the most important features in all our apps. By using this option, you can decide when the app will load when the page is accessed.
If your website has heavy customisation
Unless your store is very heavily customised, we always suggest keeping the fast loading option enabled because our app scripts will never take very much time to load. All our apps are comprised of a single script file which is minified, compressed and served from a world top CDN to ensure low latency and maximum bandwidth.
In addition, our script file is cached in the browser,so it will not consume network resources after the initial download. Basically, it works in a simple way, but provides effective results in the loading pattern of the page.
When Fast loading is enabled, the app script is added to your theme template and the app is loaded, along with all your page resources:
When Fast loading is disabled, the app script is loaded after other resources, when page loading is completed:
Please note that 'page loading' here is a technical term which is related to what a user experiences, but it's not exactly the same.
