That's one thing I already learnt :-) I'm not using any "from" clauses
in my rule sets which are used against the "big" fact sets.
That other rule set from the other thread was used in a different
context, where the number of facts is much smaller (in the hundreds).

I tried to implement something like that, but must admit that I don't
yet understand how I would do such a monitoring?! All I currently have
are custom AgendaEventListener and WorkingMemoryEventListener. I would
suspect that to implement such a monitoring, I would use
void activationCreated(ActivationCreatedEvent event);
void activationCancelled(ActivationCancelledEvent event);
of the AgendaEventListener. Could you point me to some documentation
that explains when exactly those events are triggered? Until now, I
haven't found too much doc on these aspects of Drools :-/
