Leopard Sample Code: Performance
Apple's suite of developer tools includes a number of optimization tools to help developers gather performace metrics, as well as identify and eliminate inefficiencies in their code. Code-profiling applications such as Shark show where an application is spending its time. Developers can use tools such as MallocDebug to help track down memory leaks and analyze memory use. Using these and other tools provided by Apple, developers can fine-tune their applications for high performance.
