We have a very simple formula to calculate Tableau Report Rendering Time. Report rendering time=Network time(request from URL to Report server) +Query execution time + Network time(response from SQL Server)+calculations(table column)+time taken to display the report in desired format(HTML/ pdf/ excel)  Table Calculations: These are inbuilt calculations in tableau which we normally use to calculate Percentage from or for YTD and other calculations like the measure across the table, below table and etc. Layout Containers in force spatial links between components of a dashboard. Conceptually, they allow the designer of the dashboard to format common elements and simultaneously move several dashboard objects.  One of two choices includes layout containers: horizontal or vertical.  The developer can group working sheets and dashboards from right through the pages with horizontal design containers and edit all elements at once.  Up to the bottom of your page, vertical containers enable the user to group workshop sheets as well as dashboards and modify the width of all elements. Horizontal and vertical components: We can use these to transfer all sheets or filters in one shot. However, without this, we can still generate the dashboard. It enables us to simplify our job. A common in Tableau interview questions for experienced, don't miss this one.
