Dynamic cubes heap when loading in-memory aggregates

Loading the in-memory aggregates consumes massive amounts of heap. In previous versions of Cognos when all in-memory aggregates was loaded from the source the heap consumption was far less.

We have a setup with a few cubs starting at the same time consuming in total 12GB of In-memory aggregate the heap consumes 96GB of heap during loading of the in-memory aggregats.

I question the efficiency of the operation of loading the in-memory aggregates. From a usage (reporting/analysis) perspective we only would require 36GB of heap. But in order to get the reports started we need to have 128GB of heap defined.
