Power BI high memory consumption when creating measures

This is not normal behaviour for Power BI Desktop, measures should not consume any noticable amount of memory when you create them. They might consume a lot of memory when you query them (ie use them in a visual), but not otherwise.

Can you try the following:

1. Create a new blank page in your Power BI report

2. Save your report while the blank page is selected

3. Close and re-open Power BI Desktop

4. Now try creating a number of new measures (without switching off the blank page) and see if the memory issue re-occurs

If the issue does not occur while the blank page is set as the current view then you probably have an issue with one of the measures used in one of the visuals on your normal default page (you should see the spinning progress circle in the top left corner of the visual although depending on how complex your page layout is this can sometimes be hard to see)

If the issue does continue to occur while adding measures with the blank page active then you may need to look at raising a ticket with product support https://powerbi.microsoft.com/en-us/support/pro/
