...

The time taken by the event flow to process a single event. A lower latency indicates better performance in terms of the efficiency with which the events are processed. Latency is affected by the receiver/publisher adapter type used as well as the performance configurations (see Performance Tuning Recommendations for further information). Reducing latency may involve achieving a lower throughput since  because the load handled by an event flow may need to be reduced in order to increase the event processing speed.

...

The number of events handled by an event flow per second. A higher throughput indicates better performance in terms of event processing capacity of the CEP server. The throughput is affected by the performance configurations (see Performance Tuning Recommendations for further information). Increasing the throughput may involve increasing the latency since  because an increased load of events handled by an event flow can reduce the event processing speed.
