I have a question about putting SOs into SOs and how many layers I can make before it breaks the system. And what way to do it so it doesn't.

In my system: battery park - has 13 cores - has 2 nodes - has 4 cubes - has 2 racks. I put two rack SO references into cube then 4 cubes into node, by now things are getting slow. Should I continue?

Another idea is to put each SO individually straight to main project, but it has 208 racks so that would take a lot more time. I could also make it hybrid. Ex.:putting racks into cubes and cubes straight to project.

Anyidea which way would be best for system speed andeasier to maintain in thefuture?
