The system performance package is designed to provide operational data on all significant activities involved in processing input messages from network resources. These resources may be terminals, logical units, applications, and others. By analyzing the reports produced, you can determine how efficiently the installation is running, discover where the bottlenecks are, and find clues about changes in system allocation (main storage, files, lines, or terminals) that could improve system performance.
This package can be used during installation and the post cutover phase to tune the system to peak efficiency. It provides a means for daily monitoring of system performance. The statistics generated allow long-term trends to be observed from the daily runs, in this way providing the basis for predicting growth in system load.
