Specifying Maximum Number of Concurrent Processes in Memory

The Max Jobs field in the Process Configurations dialog allows you to specify the maximum number of concurrent process instances that can be stored in memory. For example, if you set Max Jobs to 5, the process engine can only keep five process instances in memory. Any process instances created once the maximum is reached must be paged out to disk.

Specifying a value for Max Jobs causes the process engine to incur some overhead for managing the paging of process instances to and from disk. If you have sufficient system resources and do not expect incoming events to exceed the limits of your system, consider specifying Max Jobs as 0. This allows the process engine to create an unbounded number of process instances and eliminates the overhead of paging.
