PRE_PAGE_SGA determines whether Oracle reads the entire SGA into memory at
instance startup. Operating system page table entries are then prebuilt for each page of
the SGA. This setting can increase the amount of time necessary for instance startup,
but it is likely to decrease the amount of time necessary for Oracle to reach its full
performance capacity after startup.
