Outline changes and Calculation Script performance

Dear All,

I have an issue with the calculation Script performance that now last hours instead of minutes.

I will try to explain what I did:

1) I change the outline (deleting/moving some accounts from dense dimension)

2) I restructured the database (without data)

3) I uploaded the data with the new structure (upload without error and all the data at the level 0)

4) I have run the usual calculation script (3-4 minutes) and now it lasts hour.

Could someone help me to understand which could be the reason?

Thank you so much!
