IBM COBOL for MVS & VM Version 1 Release 2 Performance Tuning

Product documentation


Abstract

This paper identifies some of the factors that can affect the performance of COBOL programs when using IBM COBOL for MVS & VM Version 1 Release 2 running with IBM Language Environment for MVS & VM Version 1 Release 5 (LE). It also contains a summary of the performance experiences that we have had with COBOL for MVS & VM. The tuning methods discussed here are intended to assist users in selecting from the various options which are available for compiling COBOL programs with Version 1 Release 2 of COBOL for MVS & VM and executing them with Version 1 Release 5 of LE for MVS & VM. These methods provide the COBOL programmer with the opportunity to tune the LE run-time environment to potentially improve CPU time performance and the use of system resources.
