ODS Tables

Anytime you specify the PERFORMANCE statement in a procedure, the procedure generates an ODS table called PerformanceInfo that summarizes the performance characteristics of the procedure. The information comes from the actual characteristics used and does not necessarily match the option values specified in the PERFORMANCE statement. When you specify the DETAILS option in the PERFORMANCE statement, the procedure generates an additional ODS table called Timing.

Figure 4.1 shows a typical PerformanceInfo table in multithreaded computing mode.

Performance Information
Execution Mode Single-Machine
Number of Threads 4


If you specify the NOTHREADS system option and do not specify the NTHREADS= option in the PERFORMANCE statement, then the PerformanceInfo table contains the information shown in Figure 4.2.
