Handling the page performance issues

[Mahesh_Gunaje]

Hello All,

There might be different reason for the page performance issue. As an architect, what are the steps we need to follow to increase the page performance ?

1: Check the network tab to see the list of image file size. If its too huge, ask Author to correct.

2: Use the defer keyword while calling the JavaScript.

3: Check the Adobe Launch script.

4: Use the lazy loading feature for the different core components.

5: Enable minification in production.

Anything else, we need to take care?

Please refer to this article "AEM Performance Optimization: Best Practices for Speed and Scalability"    by @Anmol_Bhardwaj 

   Here are some additional steps you can take to enhance page performance:

1. Optimize Images:

   • Apart from checking image file sizes, consider using responsive images and the appropriate image format (e.g., WebP).
   • Leverage AEM's Dynamic Media capabilities for image optimization.

2. Caching Strategies:

   • Implement caching at different levels (browser, CDN, and server) to reduce load times.
   • Utilize AEM's caching mechanisms, such as Dispatcher caching for static content.

3. Minimize HTTP Requests:

   • Reduce the number of HTTP requests by combining CSS and JavaScript files.
   • Consider using sprites for small images.
4. Review and optimize AEM component rendering logic.
5. Utilize AEM's indexing and query capabilities effectively.
6. Browser Caching: Set appropriate cache headers to enable client-side caching.
7. Monitoring and Profiling:
   • Use AEM and third-party tools for monitoring and profiling to identify performance bottlenecks.
   • Regularly analyze logs and performance metrics to proactively address issues.
8. Responsive Design: Ensure that the website is responsive and performs well across various devices and screen sizes.
9. Optimize AEM Configuration: Review and optimize AEM configurations, including thread pools, connection pools, and other settings.
