Leopard Reference Library
The performance of Mac OS X applications and hardware devices can be measured, evaluated, and optimized using Apple's developer tools, technologies, and programming interfaces. Developers can fine-tune their applications for high performance using tools such as the Shark code-profiling application, features such as multiprocessing, and APIs such as the one for the vDSP library.
A guided introduction to improving performance in Mac OS X software.   Essential information for improving the performance of developer applications.   API references, organized by framework.
