    When you use Analyze in Excel, MDX queries are sent to the Power BI dataset. If you have a PivotTable with 10 measures, the performance is usually slower compared to a similar Matrix in Power BI with the same content. Power BI generates DAX queries.
    One of the reasons why this difference exists is that the DAX query is optimized using a process called "fusion", which includes in a single storage engine request the aggregations required for multiple measures, whereas this feature has not been implemented for MDX queries.
    Implementing fusion for MDX queries would dramatically improve the performance of many pivot tables in Excel where there are many measures in the same pivot table.

    A native DAX interface in Excel pivot-tables could be a solution

    I could not agree more with this.

    While Power BI is useful for high-level dashboarding for senior management, the real in-depth analysis normally happens in Excel. Thus any speed enhancement in Analyze in Excel will be greatly appreciated!

    Same problem, different solution...

    No idea how practical this is to implement, or whether the suggested resolution above is a better suggestion, but ultimately, the end goal for me it to make sure the user experience using Excel has comparable perfromance to using PBI.

    This is a great idea, I'll be sharing the link with my team and to clients where this would be applicable.
