SLOW Power BI Online Dashboard

My organization is experiencing really really slow performance when dashboards is published to the web. On the desktop version, it is running fine. I m using directquery. My datasets are huge, there are join queries and one or 2 of the tables have more than 23 million rows.


I have already reduced to the columns i needed. I cannot use import as it is over 1024 mb when publishing. My data resides on Azure Data Warehouse.


My data warehouse right now is using default number of DWUs. I want to know if increasing DWUs will help with directquery.


The speed is so bad that i am getting 'X' white boxes for my graphs saying that there are not enough resources to load the graphs.

Performance is very poor in direct query. you can check again by increasing DWU.

Thank you for your response.


May I have someone from microsoft to also verify this?


Since i would need to pay for additional DWUs, i need to have a confirmation that it WILL give me a better runtime when i load my dashboards online.

Re: SLOW Power BI Online Dashboard

Actually, I am pretty sure increasing DWUs will not help now. Since my on-premise server could access the data, hosted on zure DWH, fast enough for the dashboards on desktop version. It only becomes a tortise when published. I am suspecting it is a latency issue, communication between Power BI to our Azure DWH, which is hosted in SEAA. 


Anyone from microsoft can verify this?

Hi @taiyun,


It seems the issue about Power BI service itself. I would suggest you create a support ticket to contact Microsoft for dedicated support.
