Simple performance lock analysis tool (splat)

The Simple Performance Lock Analysis Tool (splat) is a software tool that generates reports on the use of synchronization locks. These include the simple and complex locks provided by the AIX® kernel, as well as user-level mutexes, read and write locks, and condition variables provided by the PThread library.

The splat tool is not currently equipped to analyze the behavior of the Virtual Memory Manager (VMM) and PMAP locks used in the AIX kernel.
