An application that uses a state machine for processing can be optimized to process objects efficiently through an alternate, executive processing module. In one implementation, for example, one of the plurality of processing modules in a given state machine can be reconfigured to subscribe to an executive processing module, which, in turn, is subscribed to all events that occur during processing of the given state machine. When the corresponding state machine is tasked with processing a client request, the executive processing module processes the client request for each subscribed processing module. The executive processing module can optimize processing of the client request for all subscribed processing modules, and can further provide human-readable output regarding processing details of the same.
