How to optimize aggregation process in Planning using Groovy - Full Aggregation (BSO)

Content

We have an EPBCS non Hybrid Application.

As the application is not Hybrid enabled, always we have to perform aggregation of cube to review top level data (BSO).

Currently, we are using Groovy to perform form level aggregation where ever needed by passing POV values to RTPs of aggregation script.

Is there any way that groovy can help us in optimizing whole cube aggregation process?

Please us know if there is any best practices of doing it.
