I was curious to see the real life impact of using fake versioning vs. native versioning on a completed model. So, I duplicated a model that had been built with fake versions, changed every module where fake versions had been used to native versions and created the same number of versions in each model.
The only difference between the two models was native vs fake versions.
Using the same number of "versions":
The Fake Versioned model has 2.7m cells and a size of 78mb
The Native Versioned model has 2.7m cells and a size of 1009mb
Clearly despite the size saving impact of switchover, there are significant size (i.e. memory) implications (as well as calculation time implications) when using native versioning.
