Considerations
The RPTOPTS option allows you to get a report of the runtime options that were in use during the execution of an application. This report is produced after the application has terminated. Thus, if the application abends, the report may not be generated. Generating the report can result in some additional overhead. Specifying RPTOPTS(OFF) will eliminate this overhead.

Performance considerations using RPTOPTS: On the average, RPTOPTS(ON) was equivalent to RPTOPTS(OFF).

Note: Although the average for a single batch program shows equivalent performance for RPTOPTS(ON), you may experience some degradation in a transaction environment (for example, CICS®) where main programs are repeatedly invoked.
