applications using MQ Series are running, you may need to consider adding memory to these pools to help performance.

yNonpersistent messages use significantly less CPU and IO resource than persistent messages do because persistent messages use native journaling support on the iSeries to ensure that messages are recoverable. Because of this, persistent messages should not be used where nonpersistent messages will be sufficient.

yIf persistent messages are needed, the user can manually create the journal receiver used by MQ Series on a user ASP in order to ensure best overall performance (MQ defaults to creating the receiver on the system ASP). In addition, the disk arms and IOPs in the user ASP should have good response times to ensure that you achieve maximum capacities for your applications that use persistent messages.
