You can see that by looking at the dependency graph [0]... everything that depends on the interfaces module instead of the data module, does *not* need the event model. In many cases you do not need this event model, e.g. in descriptor calculation where the structures do not change at all. > Profiling my project made me see that a lot of resource is spend on that > class and I am not sure whether all these events really need to be > listened to. Use the nonotify implementation of the interfaces instead, e.g. via the NoNotificationChemObjectBuilder.
