Which AEM feature can help developers measure render time if the homepage is slow?

Using Developer Mode in AEM is a powerful feature that allows developers to measure various performance metrics, including render time. When a developer mode is enabled, it logs detailed information about the request and response cycle, providing insights into how long it takes to render a page. This can be particularly valuable for diagnosing issues like slow load times on the homepage.

Developer Mode can reveal information such as which components are taking the longest to render and can help identify performance bottlenecks. It offers a granular view of the rendering process and can help in pinpointing specific areas that may need optimization, making it an essential tool when troubleshooting slow performance issues.

In contrast, optimizing the dispatcher focuses on caching and delivery strategies, generating CSV does not directly relate to performance metrics, and running reports might offer some statistical data but typically will not provide the same level of insight into the rendering process that Developer Mode does. This makes Developer Mode the most suitable choice for measuring render time.
