Take performance measurements

After your applications are running under Language Environment in a test environment, take performance measurements—especially on any time-critical or response-critical applications.

After you compare runtime performance between Language Environment and your current run time environment and have identified which applications, if any, need performance improvements, you can investigate the methods available to tune your programs and improve performance. For example, you can modify storage values using the Language Environment runtime options. For additional information, see the performance information available on the COBOL Web site.
