Just recently, maybe around Dec 12th timeframe, the reports in PowerBI service have been taking an exceptional amount of time to load.
Before: a report and all widgets would load in 2 seconds.
Now: a report isn't finishing loading until about 31 seconds.
We're connected to SQL Server live premise data source via the gateway.
There's no CPU contention on the server.
First thing I tried was upgrading to the latest version of the gateway.
(Note, even after upgrading to the latest version of the gateway, Manage Gateways in PowerBI Service still shows a message that the gateways are out of date... very odd).
We are not using PowerBI Premium.
All reports were built in PowerBI Service, on top of a model published from PowerBI Desktop.
Therefore I can't really refresh the report in PowerBI Desktop to compare performance times, as there's no PBIX of the report to open via Desktop.
Ideas on where to start troubleshooting?
