In the latest Sep'19 PBIRS update, the following slicer performance improvement has been stated. I have a lot of dropdown slicers in my dashboards. How exactly would I know if the feature below is working or not. I thought, I wouldn't see a loading icon next to those slicers anymore on initial load and they would just show up but everything appears to be running on load like before. What am I missing?
Performance improves when using relative date and dropdown slicers
If you are using the relative date slicer or the dropdown slicer, you should see some performance improvements for page loads and filtering interactions this release. The relative date slicer will no longer run any DAX queries when loading, and the dropdown slicer will only run queries when you expand the dropdown. The more slicers you had on your page, the bigger performance improvement you should see.
