How Memory Allocation Affects Performance in Multithreaded Programs [25732]
Sniffing Out Lock Contention with Several Tools

If your new server has an alarmingly lower transaction rate than you had anticipated, Rickey C. Weisner suggests that you look first at lock contention in the memory allocator. His article demonstrates the use of prstat to determine whether there is lock contention. Demonstrated as well is the use of Professor Emery Berger's MT-hot allocator named Hoard, and of the mtmalloc (both old and new), and the libumem memory allocators. The question of which is best is answered by Weisner's use of a test harness, which appears to give the edge to the new mtmalloc.

Anatomizing an Oracle Solaris Binary File [25224]
The Tools and Techniques You Will Need

When application object files and executable binary files become unhandily large, it is helpful to be able to see inside such files. In order to do that it is necessary to know what tools are called for in such an inquiry and which parts can be reduced in size. In her oracle.com/technetwork post Miriam Blatt discusses these issues, reviewing the contents of binaries and the tools that are available to read, extract and delete sections. She concludes with a discussion of the effect on binary file size of compiler flags and how to reduce the size of the executable.
