Like Stefan asks, what do you mean by "object"?  Servant or object
reference?  Whatever you mean, things are not anything like as simple
as you seem to expect. For each CORBA object, there are several C++
objects involved. The size of the objects can vary for a number of
reasons.

I suggest a far more profitable way of evaluating the size of whatever
it is you are trying to measure is to plot a graph of process size
against number of objects. That will give you a figure for the average
size of an object.

Cheers,

Duncan.
