Hello Shiwani,

Beside the time and resources for retrieving data, there is time and resources for generating the report that visualizes the data with native objects for the selected media(HTML for web preview, Image for design-time preview, PDF and etc.).
In addition, each data item executes its data-retrieval method on its own.

Please go through the suggestion in Performance Considerations. Also consider switching to data-binding approaches based on expressions like in How to Databind to Collection Properties and Use DataObject as a datasource for nested data items (Table, List, Crosstab, Graph. These approaches save you from re-retrieving the data for each data item.

Regards,
Stef
