I've recently noticed that the refresh time for my Power BI semantic model has increased from 30 minutes to over an hour. The associated dataflow takes about 25 minutes, but the remaining 40 minutes of the process is unaccounted for, and I can no longer locate the previous version of the file to compare.
Can anyone suggest tools or methods to analyze what's happening during the refresh process? Specifically, I'm looking to identify which steps or queries are contributing to the increased time so I can target and optimize them. Any advice on detailed logging or monitoring techniques within the Power BI Service or external tools would be greatly appreciated.
Thanks in advance!
