[sruthi]

Hi,
i have a requiremnet to create a dashboard with mutiple tabs.
Each tab contain mutiple charts and filter that sholud filter to individual filters + global filters.
I Have started with a single tab that contain 2 chrts n a list .iam working on making them  filter to the individual  and global filters .But iam facing certain performance issues. the mht file is taking about 8- 12mins to create .mht file..and the rendering time for the .mht file is also high.
i believe if you could share any sample  report specifiation of a active report dashboard( attached sample) it would be really helpful guide for me. i tired to login to below link as mentioned in the post :
