Child vs nested package : efficiency matter

["Yannick Duchêne (Hibou57)" <yannick_duchene@yahoo.fr>]

Hillo,


For some reasons, I've turned some nested package -- packages nested in  
the body of package -- into a set of child packages instead.

I've noticed the application's execution time is now an average of 125% of  
that of the old implementation.

The implementation did not changed otherwise and is still the same.

What can make invokation of subprograms slower when the subprograms are in  
a child package rather than in a nested package ?

Note: this is with optimization enabled -- with -O -- and both old and new  
implementation was compiled with the same options.

I can't explain that and can't imagine a reason why. That's a mystery to  
me.
