Filtering Data works slowly

In the dashboard Navigation and other objects are running fine however filtering is working very slow. It is taking almost 40 seconds for any particular filter when i click on any list box where as dashboard loads in 7 seconds.

Try analyzing the document with Document Analyzer V3.2 Update to see which parts are impacting performance.

We have already setup analyzer V3.1..in that i can see some data elements taking memory..is there any way we can see if any particular expression is causing this or handling data elements will help in our case?

Yes. Test the expressions individually to see what each contributes to the calculation cost.

Thanks i am getting idea about calculation cost for each expression. Putting any particular expression into variable will help?

That depends. It will still need to be calculated. But it may make a difference if it doesn't need to be calculated at the row level, but can be calculated at the document level.
