What is the purpose of the 'Speed index' in Dynatrace metrics?

The purpose of the 'Speed Index' in Dynatrace metrics is to indicate perceived loading performance. This metric is specifically designed to measure how quickly the contents of a page are visually populated on the user’s screen. The Speed Index reflects the experience of the user during the loading phase, capturing the time taken for each visible element to appear on the screen compared to the overall load time. By focusing on perceived performance, this metric helps teams understand how users perceive the speed of their application, allowing for targeted improvements for enhanced user satisfaction.

While memory usage, server response time, and user engagement are important metrics in performance monitoring, they do not specifically measure how quickly users perceive the loading of the content on web pages like the Speed Index does.
