Suman,
Thanks for your quick response on this issue.
Here we are using this same setup of folders in production with patch 9 and jaspersoft version is 6.1.0. There it take only 1.3 minutes to load the repository.
While upgrading, we had used the export file (UI export) from Production and upgraded. Reports are working fine. But the repository is taking 6-8 minutes to load.
Am attaching a screen shot. Those are not user folders. We have created different folders to implement data level security in reports.
Thanks,
Agin
