Power BI Desktop Refresh Slow
jillian are the numbers for any of these queries moving?
If you go to the Task Manager, how many Microsoft.Mashup.Container*.exe can you find there, and are any of them busy?
Have you tried to disable relationship detection in the settings dialog?
The data changes once per hour for this particular dataset. The entire .pbix is only 3.8MB including the data. I'm currently seeing 3x Microsoft.Mashup.Container.NetFX40.exe's running.
I tried disabling both Import / Autodetect Relationships as well as disabling Type Detection. I'm seeing the same slowness on this latest build.

jillian, one other thing to turn off (just to diagnose) in the settings dialog:
Current File->Data Load->Auto Date/Time
With this off, try refresh again
I disabled Data Load -> Auto Date/Time and voila! That fixed it!
Thank you. Wonder what changed in the latest build that's causing this. I havent ran into this problem before.
jillian Well that only explains the reason, not the cause. We'll investigate this internally.
I'm guessing your data probably have many columns of date/time type, so behind the scenes we are trying to create a date table automatically, which takes time. Disabling the auto date/time feature means you'll probably need to manually create a date table in the model. There are many ways to do this, and many posts about it on this forum.
