Leopard Reference: Carbon
The performance of Carbon applications 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.
