In case of local events both CPU & memory are consumed. CPU is used 
because an event object has to be constructed and processed by a local 
listener and stored in  EventStorageSpi [1].
Additional memory is occupied by created event objects and 
EventStorageSpi implementation.

Yes, if a remote filter succeeds then an event is delivered to a local 
node's local listener that started the remote filter.
