I would check the response from Cor I have quoted below.
I realize this question is a bit old. I just came upon it by searching for performance.
Performance can be tough to narrow down. But since it has already been noted that the workbook performs well in Desktop it is likely due to to the Server / Network environment.
Both Tableau Desktop and Tableau Server use the vizql process for rendering views, though Tableau Sever has other components.
One thing to try to determine if the Server machine is under resourced is to install a copy of Tableau Desktop on the Tableau Server machine open the workbook and take a performance recording.
If the workbook performance slow it is likely due to the Tableau Server environment.
Some other information that would be helpful:
* What version of Tableau Server is being used? Most minor releases contain performance improvements.
* What browsers versions have been tested?
* Are you experiencing the same slowness from the office on your internal network? Or is it only slow when you located somewhere else?
* Where is Tableau Sever hosted relative to your location?
* Is Tableau Server installed in a VM environment? And if so, are resources being shared?
* Does the workbook always perform slow when loading in the browser? Or is it only slow at certain times of the day?
I believe the above is a good place to start to help things get narrowed down.
While we would expect Tableau Server to maybe be a little slower, what is being described here sounds different.
Hope this helps!
I have this same question/issue. What is noticeable is that some dashboards on the same server 10.5.2 are extremely response where as others take 5+ seconds for the tooltip to show. When you look at the dashboards, they appear to be setup the same way.
