Pro's and Con's on Data model Acceleration. Please advise why or why not , should one accelerate them all?

Why should data models all be accelerated? What about the built-in Data Models?

I disagree with the premise that all data models should be accelerated.  One should only accelerate the data models one uses.

Pros of acceleration: faster access to data

Cons: additional storage; additional scheduled searches
