Which process is recommended to be installed alongside the Application Server for better performance?

In the context of Tableau Server architecture, the recommended process to install alongside the Application Server for better performance is the Metrics Service. This service is designed to enhance the monitoring and performance analysis of Tableau Server. By collecting and aggregating performance metrics, it allows for more informed decisions regarding resource allocation, scaling, and optimization of server processes, leading to improved overall performance.

The Application Server handles requests from users and manages sessions, while the Metrics Service complements it by providing visibility into how well these processes are performing. When both are deployed, administrators can access detailed metrics on server activity, which aids in tuning the server for optimal performance and user satisfaction.

In contrast, while the other options such as Data Source Properties, Backgrounder, and Cluster Controller might contribute to different aspects of Tableau Server functionality, they do not specifically serve the purpose of enhancing performance metrics and monitoring in conjunction with the Application Server to the same extent as the Metrics Service.
