Off-Peak Hours:

Knowing the off-peak hours helps in scheduling maintenance and updates during times that have the least impact on the users. This reduces downtime and ensures high availability during peak usage times.

Understanding Lazy-Loading: Lazy-loading is a web performance optimization technique that defers loading images until they are in the visible viewport, i.e., the part of the webpage currently visible to the user. This improves the initial page load time and reduces unnecessary data transfer for images that might not be viewed.

Implementation in AEM:

Core Image Component: Adobe Experience Manager’s Core Image component supports lazy-loading. Developers can enable this feature through component configurations or customizations.

HTML and JavaScript Integration: Lazy-loading can be implemented using theloading="lazy"attribute in HTML5 for image tags, or through JavaScript libraries that provide more control over the loading process.

Business Perspective:

Improved Page Load Time: Lazy-loading enhances user experience by reducing initial load times, especially on pages with many images. This leads to faster rendering of above-the-fold content and improved page performance.

SEO and User Engagement: Faster loading pages contribute to better SEO rankings and improved user engagement as users are less likely to abandon slow-loading pages.

Addressing Common Misconceptions:

GIF Animation: Lazy-loading does not affect the animation speed of GIF images; it only defers their loading until they are needed.

User Interaction: Images will load automatically as the user scrolls to them, without requiring any clicks.
