If you are running services and P6 on the same server, you should keep the defaults. If you have store period performance work that needs to be done immediately, you should set the Interval low (e.g., 10s) and the Concurrent Threads high (e.g., 20). Remember that if the server is actively running store period performance work, all users will experience delays in the application.
To set your store period performance settings:
Open the P6 Administrator application.
In the Configurations tab, expand your configuration.
Expand Services/Store Period Performance.
In the Interval field, enter the amount of time the PeriodPerformance service will wait before running the next available job (in 1d1h1m1s format - specifying only numbers without letters implies milliseconds).
The default is 10s.
Enter anything from 1s-24d20h31m23s647.
In the Concurrent Threads field, enter the number of processes used for the PeriodPerformance service on this server. A value of 0 indicates that the service is not available on this server.
The default is 2.
Enter anything from 0-20.
In the Active Mode field, choose true if you want jobs processed continuously until all jobs finish. Choose false if you want each job processed according to the Interval.
