Report renders too slow

Hi!

We have a powerbi-report embedded in a webpage with a iframe.

Only trouble is that it renders to slow (>10 seconds), and the user cant navigate the webpage while the report i rendering.

I there anyway to make rendering faster?

What would be the best alternetive to examin:

- Improving memory or CPU on report server

- Make a less complex report with fewer tabs

- Improving the performans of the data source (we use a tabular cube)

Any pointer would be greatly appreciated!
