After upgrade to 15.4, the Jaspersoft reports is running slow
1. Clear out the browser cache (steps vary by browser)
2. At JasperSoft tomcat server clear the 'Temp' & 'Work' folders and remove the temporary files by removing all the temp files from %TEMP% directory.
If problems persist…
3 Flush the cache at Load Balance layer as well; specially if its not cleared on regular bases.
