The Java Virtual Machine (JVM) includes many features that improve the performance of applications. One of them is the ability to compile Java bytecodes into native instructions, resulting in a significant speedup over bytecode interpretation. Another is the ability to use optimization techniques to reduce code size and speed up application execution even further. Java programmers sometimes try to improve application performance by using unusual or awkward code patterns, many of which are unnecessary given these features.
In this talk we'll review the JVM execution model, discuss bytecode compilation, and work through several key optimization transformations to see how the JVM can improve application performance without requiring any special coding patterns or techniques.
