A.1.4 Notes When Executing a Large Number of Jobs in Multiple SubsystemsIt may result in performance deterioration if you create multi-subsystems environment using the createsubsystem command and starting a large number of jobs immediately after that, since environment created on a same disk.
When operating a large number of jobs, it is recommended to distribute the Jobscheduler database directory and the Job Execution Control spool directory to different disks for each subsystem.
For details on how to distribute the database directory and spool directory to different disks for each subsystem, see "13.3 Distributing the Database Directory and the Spool Directory ".
