Session Evaluation

During this presentation, we would like to share some of the success stories of Mainframe application tuning which will focus on arithmetic data types, compiler options, and dataset blocking. By classifying improvements into three categories—without code changes, with code modifications, and through recompilation—attendees will gain actionable insights into enhancing efficiency and reducing resource consumption. These examples demonstrate how Small optimizations yield significant improvements and demonstrate how measurement tools have such an important role in the present day performance improvement attempts on the mainframe.
