LEGACY PROGRAM CODE ANALYSIS AND OPTIMIZATION

摘要

A method for analyzing and optimizing legacy program code is disclosed. In one embodiment, such a method includes logically dividing legacy program code into multiple sections and possibly subsections. The method then instruments each section with a counter that increments a value each time the respective section is executed. The legacy program code is then executed over a specified period of time on a specified number of test systems. The values are then gathered from the counters and analyzed to determine relative importance of the sections. In certain embodiments, this analysis generates a list of sections that are dead. The method then removes, from the legacy program code, sections that are dead. A corresponding system and computer program product are also disclosed.
