This paper was produced to assist you in improving the performance of your OS/2 system by providing information on OS/2 Warp 4, its various subsystems, and practical performance tuning tips and techniques. It begins by familiarizing you the new features and enhanced functions of OS/2 Warp 4. It will then introduce you to the concepts and terminology needed to successfully tune an OS/2 system. You will learn to recognize the symptoms of many common performance problems. You will also learn how to create and use a repeatable process for analyzing a system performance problem and understand the many tuning parameters and techniques used to
fully optimize your system. The tuning tips and techniques are divided into 3 sections targeted to different levels of complexity: basic OS/2 tuning, advanced OS/2 tuning, and tuning tips for a networked OS/2 workstation.
This paper documents the procedures used and knowledge obtained from performance evaluation and measurement activities. Some procedures have been recorded in documents previously published by OS/2 development and support groups within IBM. It should be considered a working document subject to forthcoming changes without notice as additional information is obtained.
