Abstract: A device selectively executes native machine code of a computing method in an application. Prior to execution of the application, a predicted usage level of the computing method is determined based on available statistical analysis data of the computing method. According to a determination of whether the predicted usage level exceeds a threshold, a selector selects executable code of the computing method for execution. The executable code is the native machine code or bytecode of the computing method. When the computing method is called during execution of the application, the selected executable code is loaded from non-volatile storage into memory for execution by a virtual machine. Furthermore, runtime usage level of the computing method is monitored to determine whether to switch from bytecode to native machine code execution.
