Here are the basic steps: Test the workbook in Tableau Desktop. Does it perform well? If yes: Test the workbook in Tableau Desktop on the Tableau Server machine. Does it perform the same as it did on the previous machine? If yes: Publish the workbook to Tableau Server, and find a time when there is low-to-no usage on the Tableau Server. Go to the published workbook. Did it perform relatively the same as the test in Step 2 (within 1-3 seconds)?  If yes: Test the workbook during a time of high usage on the Tableau Server (either natural or do load testing using Tabjolt) If it is slow in Tableau Desktop, it will be slow in Tableau Server. The main principle we use to isolate the issue is “ If it is slow in Tableau Desktop, it will be slow in Tableau Server “. You might alternatively think of this in te...
