Hi SeeraNavya,

It is expected that the huge content in a single page or section will have a performance impact at runtime. However, we can improve the same by adding some design changes to existing section. Below are the different options available Out of the Box to improve the performance.

1) Try defer load the contents based on the priority. (Even though, the page has the huge content end user may not be able to use everything at time so load the content when ever user requested for it. ) In Pega, Defer load contents option available at dynamic layout.

2) As your query says that you are using grids, you can configure pagination for grids which will improve performance. (You can use Progressive pagination for better user experience or any other pagination format)

When you apply pagination try using sorting and filtering configuration on grids which will give better usability to reach the most recent item in the grid.

3) As your query says more about including section, you can make use of defer load content option the section include configuration. This will defer load the contents. Hence, user may not need to wait to load such big section to load.

Hope this helps, Please feel free to reply if you have any more details.

Thank you,

Tilak
