What does grouping by resource type allow you to see?

Grouping by resource type provides insights into various categories of resources, specifically identifying the different types of assets being loaded by a webpage or application. This categorization can include elements such as images, scripts, stylesheets, and other resource types. By segmenting resources in this manner, developers and analysts can better understand how different types of assets contribute to page performance, load times, and user experience.

This level of granularity is crucial for performance optimization, as it allows teams to identify which categories of resources may be causing delays or issues. For instance, if images are taking significantly longer to load compared to scripts or stylesheets, targeted optimizations can be implemented to improve loading times for that specific category.

The other answer choices provide valuable information but focus on broader concepts or different aspects of resource analysis. Overall resource usage, load order and timing, and total resource counts are important metrics, but they do not specifically capture the detailed categorization of resources that grouping by resource type offers.
