David,
I'm starting to hesitate before posting my question.
When you say only one copy of the service program code will be loaded into memory, would that mean the whole code for all the functions it may have, even if the calling program only used on of those functions?

This is not specifically a performance-related question: we're just
wondering if, for the System, would be no diff beteween the two
approach, or if we're wasting resources just to keep item in a sigle object.
I don't think it's that big of a deal to have heavier service programs ... as long as things are broken up logically.
Keep in mind that only one copy of the service program code will be loaded into memory ... and every job that uses the same service program will access that single instance of the code.
