Report is becoming slow after adding new customers - Power BI

[Abishek]

Hi,
I have a power bi report developed for single customer. it is super fast at this time. As soon as I include 10 more customers, my report becomes slow. What will be the reason for slowness thought I’m viewing my report customer wise ?

@Abishek Check with query performance 

when you will run you will get to know is this because of measure, visual or anything. check steps who are taking maximum time.

Or

go to transform data -> tools -> diagnose steps to know 

I hope this will help

regards,
