Jasperserver V8.2.0 is loading reports slowly as compared to previous version. Both the old version and new version ( V8.2.0) running on servers with same system configurations ( 32 GB ram, 8 Cores, Ubuntu ), but previous version seems to be performing well for same type of reports.
Also found issue with loader, the loader diaglog box hides before reports gets completely render on webpage.
After debugging found that, rest_v2/reports api taking more time than previous version, it seems multiple request at backed in chucks until data gets fully loaded, Also two new paramters added with "rest_v2/report" api, freshData and "TotalCount" which were not present before.
Please look into it as it is not giving good experince. Seems to be bug in jasperserver V8.2.0.
