New Memory Allocation Algorithm MALLOCTYPE=watson

AIX 5.3 introduces a new memory allocation algorithm, MALLOCTYPE=watson. The Watson malloc() setting can provide improvement over the default malloc in areas of memory fragmentation and performance in massively multithreaded applications, particularly with respect to small requests. New features are added to the malloc debugging facility to aid in the diagnosis of memory allocation problems, and malloc debugging capabilities are integrated into the dbx symbolic debugger.
For more information about the malloc debugging facility, see "System Memory Allocation Using the malloc Subsystem" in AIX 5L Version 5.3 General Programming Concepts: Writing and Debugging Programs in the AIX Information Center.
