How to do Performance Testing in Tableau?

Start with a performance recording: Help → Settings and Performance → Start Performance Recording, use the workbook as a reader would, then stop. Tableau opens a workbook breaking the time down by query execution, layout, rendering and connection.

Read that before changing anything. The intuitive fix is often the wrong one — if 90% of the time is query execution, restyling the dashboard achieves nothing.

On Server, the same recording is available per view, and the administrative views show load over time and the slowest views across the site.

For load testing specifically, TabJolt simulates many concurrent users against Server. It is a community tool rather than a supported product, so it needs setting up separately.
