Visuals on power bi service loads slow

The visuals on the power bi service load slow. It takes around 5 minutes for all the visuals to load completely. Some visuals load faster than other visuals but overall loading is slow. The initial loading as well as when I change to other reports the visuals just show the loading sign.

I am using Direct Query method.

I have around 200 measures and 12 tables in the report.

I have 5 reports in the published report.

Can someone let me know how can I make them load faster? Are there any caching techniques I can use?

Thanks.
