If the data is setup correctly (e.i. not mixed in with other stuff) then 
the only the data that is called for will be paged in. I'm having a hard 
time thinking of a situation where this would be less than ideal.

The only case I can think of is where the data can be compressed a lot and 
you page in compressed structures and then expand as needed into memory. 
Most simple systems would read in the same data in a (probably bulkier format) 
but do it all before the first access.
