Slow report rendering with large datasets and subreports in .NET web app
Posted: Sun May 17, 2026 3:43 am
Hi,
I’m currently working with Stimulsoft Reports in a .NET web application and noticed that report rendering becomes noticeably slower when loading larger datasets with multiple subreports and charts.
Has anyone found good practices for improving performance in this kind of setup? For example, is it better to preload data into business objects rather than relying on direct database connections inside the report? Any tips regarding caching or report optimization would also be appreciated.
Thanks!
