Debugging and optimizing Adobe Experience Manager (AEM) page performance involves a series of steps to identify bottlenecks and apply best practices. Here's a structured approach:
1. Monitor Performance Metrics
- Page Load Time: Measure how long it takes for a page to load fully.
- Time to First Byte (TTFB): Check the time taken by the server to deliver the first byte of the page.
- Core Web Vitals: Focus on metrics like Largest Contentful Paint (LCP), First Input Delay (FID), and Cumulative Layout Shift (CLS).
2. Use AEM's Built-in Tools
- AEM Reports: Utilize the built-in reports for performance analysis.
- Request Performance Tool : Available in AEM, this tool helps to analyze the request performance.
- AEM Developer Mode : Use this to get insights into the components and their rendering times.
3. Analyze Components and Templates
- Component Analysis : Identify slow components. Check for inefficient code, excessive server calls, or large payloads.
- Template Optimization : Ensure that templates are optimized and do not include unnecessary elements or logic.
