PBI Embedded

[poojithap]

I'm embedding Power BI reports into a React/Node.js application using service principal authentication. While the embedding generally works, I'm observing a noticeable 'buffering' or loading time before the report becomes interactive. My current setup fetches an access token, then an embed token, and then uses powerbi-client-react to display the report. I'm also caching the embed URL on the backend.

What are the most common causes of significant loading times for embedded Power BI reports, and what are the best practices or optimization strategies (both on the backend for token generation/fetching and on the frontend for rendering) to minimize this buffering time?

Hi @poojithap

Thank you for reaching out to the Microsoft Fabric Forum Community.

Slow loading times for embedded Power BI reports are typically due to complex report designs, frequent token generation, and frontend rendering delays. To enhance performance, cache both the Azure access token and the embed token on the backend instead of generating them each time. Simplify report visuals, avoid heavy DAX or unused filters, and delay frontend rendering until the embed token and URL are ready.
