Optimizing dashboard use
The following considerations assist in optimizing a dashboard:

Use data object store files instead of data object design files to avoid long queries when on-demand data is not required. Object store files are cached in the BIRT iHub, enabling multiple users to quickly access data.

Display BIRT report document files in place of BIRT report design files when possible. This avoids the time necessary for data population and rendering of a report design file.

Activate dashboard auto refresh only when monitoring changing data.

When using data selection gadgets, consider using data objects with optimized indexes for quick population of the gadget.

Use data selection gadgets or summarized data in place of large reports.

Consider BIRT design features available in BIRT Designer Professional for advanced chart interactivity and layout control. For example, adding a bookmark to a grid element in a BIRT design file enables the display of multiple BIRT elements. Multiple BIRT visualizations can be put into the grid. A Reportlet gadget can then embed the bookmarked grid element for display on a dashboard.
