How to reduce the load by "user-defined aggregation"

In the star schema shown below, it was possible to make one of the fact tables bidirectional in order to link the fact tables without the key of the master table. However, as the number of data and parameters increases, the calculation of the Power BI measure becomes very heavy. I would like to know how to deal with this problem

So I found "User-defined aggregations". Is it possible to reduce the load by this?

@Anonymous , You have a concept of aggregations, but the table need to be in direct query mode for an import aggregate

Thank you for your reply.

It turns out that this is not a relation issue, but a solution to the issue with direct queries.

thank you.
