title: SSRS 2019 - slow rendering of ALL reports
body: <p>I recently upgraded my SSRS site from 2014 to 2019.  No issues upgrading, but one annoying thing is happening; every report is taking an extra 10-20 seconds to start the display process, and it happens every time.  When I click on a report, the &quot;loading&quot; box appears for 10-20 seconds.  Then the &quot;loading&quot; box changes fonts and then the report renders.  In the case where the report has parameters for the user to fill in before rendering the same thing happens before the user can fill in the parameters.  I haven't found any errors in the logs, but once thing I noticed is that the messages in the logs are recording this extra time, like this example (note the 14 second time lapse in the messages):</p>

  <p>I suspect an issue with the SSRS 2019 install, but I can't find anything wrong; any ideas?</p>
