Introduction
Magento is a powerhouse offering scalability, customizability, and integration capabilities that any eCommerce business would love to leverage. These capabilities come packed with equally strong challenges in terms of performance.
So, make performance optimization a key phase of your Magento 2 store’s development.
Here are some of the statistics that emphasize the importance of performance optimization:
Did You Know?
- 47% of consumers expect a web page to load in 2 seconds or less.
- 40% of people abandon a website that takes more than 3 seconds to load.
- A 1-second delay in page response can result in a 7% reduction in conversions.
- 1-second delay reduces customer satisfaction by 16%.
Load ‘Above-the-Fold’ Contents First
‘Above-the-Fold’ is the content that users get to see first. It is the first part of the page, after which a user scrolls to see the remaining contents. This can be done by the technique given below:
Refrain JS from Loading Upfront
Contents in a web page must be given priority over JS code. When a web page’s above-the-fold contents load, the JS code loads simultaneously, increasing load time.
Refraining JS from loading upfront means deferring the parsing of JavaScript code. This can be done by moving JavaScript code to the bottom of the page and can be achieved with the help of third-party extensions.
JS Bundling
Why is Magento 2 JS Bundling Important for Achieving High Page Speeds?
As a platform that supports growing businesses to enterprise-level brands, Magento is loaded with built in features backed by tens of thousands of JS files.
There are hundreds of JS files that need to load per page. Avoiding unnecessary JS files from loading for each page will result in reduced load times and improved page speed.
Advanced JS Bundling
‘Advanced Bundling’ is an innovation of the ‘Basic Bundling’ technique used to overcome the shortcomings of the latter. Advanced Bundling combines the packages, creating a single, large file and requires a page-specific approach for building bundles. Home Pages, Category Pages, Product Pages, Carts etc., must be optimized for JS bundling separately. A page-wise approach helps in keeping only the necessary JS files required for the page.
Advanced Bundling also provides provisions to load the CSS files before JavaScript. This technique renders page contents faster to users. Advanced Bundling reduces the number of requests drastically, reduces the size of Javascripts loaded by sticking to page-specific files.
