Virtualize objects to alleviate memory usage

Greetings,
I am testing this flowitem generation logic but I encounter that too many flowitems are occupying memory in the model. In fact, when I try to open the Memory Profiler to check where the most memory is being used, it will not even open. Doing some research about this issue I have seen that others were able to cut down on memory usage through virtualizing objects. I would like to know how object virtualization works step by step and how could I apply it to this model. Would that be an adequate fix for the memory usage issue?

Attached below are the model and the Excel archive that feeds the logic.

Just turn off "Show Contents" of the queues under "More Visuals" - the problem is you're trying to draw 800K items, not that it's using too much memory (10GB). Why do you need this many in a queue?
