What is the function of the dispatcher in managing website performance?

The function of the dispatcher in managing website performance is centered around content delivery. The dispatcher serves as a caching and load balancing tool in Adobe Experience Manager (AEM) environments. It accelerates the delivery of content to users by caching responses from the AEM instances, which reduces the number of requests that hit the backend servers. By delivering cached content quickly, the dispatcher improves load times and overall performance for the end-user experience.

In addition to caching, the dispatcher can also distribute incoming traffic across multiple AEM instances, helping to manage performance during high traffic periods. This load balancing ensures that no single instance becomes a bottleneck, thus maintaining optimal website performance.

While other options may touch on aspects related to website management, they don't encapsulate the primary role of the dispatcher in the context of performance. For instance, optimizing mobile loading, controlling access to assets, and enhancing SEO focus on different areas such as user experience, security, and search engine visibility rather than specifically addressing how to manage and deliver content efficiently.
