ABSTRACT:
Methods, systems, and media to increase efficiency of tasks by observing the performance of generally equivalent code paths during execution of the task are disclosed. Embodiments involve a computer system with software, or hard-coded logic, that includes reflexive code paths. The reflexive code paths may be identified by a software or hardware designer during the design of the computer system. For that particular computer system, however, one of the code paths may offer better performance characteristics so a monitor collects performance data during execution of the reflexive code paths and a code path selector selects the reflexive code with favorable performance characteristics. One embodiment improves the performance of memory allocation by selectively implementing a tunable, linear, memory allocation module in place of a default memory allocation module.
