Power BI Pro Web is extremely slow

Has anyone else notice PowerBI Pro is extremely slow over the last week 12/10/18 to present day?  We have been getting the following messages off and on.  Reports sometimes run okay and other times they fail and it seem to be the reliability (lack) of the MS service.  If we run via the PowerBI Pro Desktop things run much faster and don't fail.  Over a month ago, we didn't have the issue, but it's getting worse as the days/weeks go by to the point it's unusable.  So far MS support does not seem to do anything and claim

Our Product team pushes improvements and features on weekly basis. These improvements are planned well in advance.

Hey Kevin, 


We have been experiencing very similar issues. The Power BI Service has been very sluggish across different users PCs, different PBI Service Tenants, and different PBI Regions for the past week. We haven't seen any errors but I am sure there is a timeout error for actions in the PBI Service that hit a time threshold which is what you are probably experiencing. 


I am guessing that this is an issue with updates to PBI Service and MSFT is working on resolving this issue. The question is how soon...








Do you get the perfromance issue in all Power BI reports? What web browser do you use? Please try different web browsers and check if same issue occurs.

Thanks for the reply.  I've used Safari, IE and both are experiencing the same issue.  I've also gone against two PowerBI workspaces with the same results.  This was not an issue a mont ago, but over the last month perforamnce has degraded.  As mentioned if I run the reports through PowerBI Desktop they run much faster and most without issue.  


In my ticket with MS I provided traces via Fiddler and within those traces there are 404 Errors.

@kwyoung001 @DavidKett,

I am unable to reproduce this issue on my side, I would recommend you open a support ticket in Power BI support site.
