Powerbi report optimization

[simona0808]

Hello everyone. I have 4 Power BI reports with 3-5 pages each. My client wants me to combine these pages into one big report, resulting in 20+ pages. What I am concerned about is the speed of the report. The connection comes from DirectQuery mode, and I use one parent table and different child tables for the relationships. Do you think that is possible? If yes, can you give me advice on how I can meet the client's requirements without impacting the speed of the report?

The number of pages in a report doesn't matter for performance.  Each page is rendered separately, and only when requested by the report viewer.

This is more a problem of maintenance and exporting/printing - for example you can only export up to 50 report pages.
