Hi Anonymous ,

 

Calculations that need to cross relationships, especially on large tables, will have a noticeable hit on performance. 

  • Avoid relationships on calculated columns and unique identifier columns.
  • Try setting “Assume Referential Integrity” on relationships – in many cases, this can significantly improve query performance. 
  • Avoid both-directional relationships if possible.

    Hi, 

     

    Thank you for the response. I think that I need to clarify a bit.

     

    My problem is focused on getting the data via the query editor. When accessing Salesforce Objects via the query editor theere is a choice to include so called "Relationship columns". These can then be expanded to show the columns and selecting the ones that are needed. 

     

    So there is no calculation involved.

     

    There is a huge difference. A Salesforce Object of 150 000 rows will load in 2-3 minutes. If I expand one of the relationship columns that load time will go to 15 minutes or even longer!

     

    What can I do to improve that?
