The memory footprint can only be lower if multiple applications are in =

memory that can use the same packages.

Even then, there will only be savings if the amount of code that can be =

smartlinked is small.

Example: Let's say an LCL package is 10MB. 2 applications are 2MB when =

smartlinked, and 100kb when linked against the package. (The heap can be =

ignored in this discussion because its memory usage does not differ =

depending on packages being used.)

Memory use with packages:     10MB+2*100KB =3D 10,2MB.
Memory use with smartlinking: 2*2MB        =3D  4MB
