ssas - 将 MDX 转换为 DAX 查询时的性能问题

Question

我有一个 MDX 查询，我想将其转换为 DAX 以提高性能，但结果不如预期，MDX 需要 11 秒才能完成，而 DAX 需要 34 秒。任何改进 DAX 查询的建议

MDX 查询:

SELECT
{
    [Measures].[Internet Total Sales]
} ON COLUMNS,
ORDER(
    NONEMPTY
    (
        {
            [Product].[Model Name].[Model Name].AllMembers *
            [Product].[Product Line].[Product Line].AllMembers *
            [Product].[Product Name].[Product Name].AllMembers *
            [Customer].[First Name].[First Name].AllMembers *
            [Customer].[Last Name].[Last Name].AllMembers
        },
        {
            [Measures].[Internet Total Sales]
        }
    ),
    [Product].[Model Name].CurrentMember.MemberValue, ASC
) ON ROWS
FROM [Model]

DAX 查询:

    FILTER

        SUMMARIZE
        (
            CROSSJOIN('Product', 'Customer'),
            [Model Name],
            [Product Line],
            [Product Name],
            [First Name],
            [Last Name],
            "Internet Total Sales",
            [Internet Total Sales]
        ),
        NOT ISBLANK([Internet Total Sales])
    )
)
ORDER BY [Model Name] ASC

谢谢。
