Preparing an initial OPT

There are several approaches to preparing an initial OPT.

Use the default OPT.
Modify the default OPT.
Create a new OPT.

If you plan to use these constants for purposes other than those suggested in this information, observe the following limitations:

Actual customer workloads and performance may vary. For a more exact comparison of processors, see the internal throughput rate (ITR) numbers in Large Systems Performance Reference (LSPR).
CPU time can vary for different runs of the same job step. One or more of the following factors might cause variations in the CPU time: CPU architecture (such as storage buffering), cycle stealing with integrated channels, and the amount of the queue searching (see z/OS MVS System Management Facilities (SMF)).
The constants do not account for multiprocessor effects within logical partitions. For example, a logical 1-way partition in an S/390 9672, Model RX3, has 1090 service units per second, while a 10-way partition on the same machine has 839.3 service units per second.
