ProcessEventsInOrder Element (ADF)
Specifies whether Notification Services uses quantum sequencing or subquantum sequencing to process event and subscription rules.

Remarks
The ProcessEventsInOrder element configures quantum or subquantum sequencing. When using quantum sequencing, Notification Services fires the event and subscription rules once per quantum. When using subquantum sequencing, Notification Services fires the event and subscription rules when each event batch arrives, which might happen multiple times per quantum. Quantum sequencing is more efficient; subquantum sequencing ensures that events are processed in order as they arrive.
To use quantum sequencing, set ProcessEventsInOrder to false. To use sub-quantum sequencing, set ProcessEventsInOrder to true.
