The question is to define what can be considered 'related'. If the methods
involved are always called independant of each other but are very similar
business processes then do we consider them related and thus place them on
the same bean. Also consider that there might be varying trafic load on
each of the functions... doesn't placing them in separate beans give us a
chance to fine tune the performance of the application?

This is not really an issue. The number of _instances_ in memory only
depends on the number of inflight calls (assuming stateless SBs, otherwise
the semantics change). The number of calls does not depend on your
partitioning.

If they are related, put them together. If they are unrelated, separate
them. Performance is not a factor here.
