Survey on Java Optimization Techniques

Java has emerged as a dominant programming language widely used in a large variety of application areas.However,its architectural independent design means that it is frequently unable to deliver high runtime performance.This paper presents a survey on various approaches developed to improve Java performance,including static,just-in-time and dynamic optimization used in Java optimizing compilers,high-performance Java virtual machine,domain-specific optimization techniques and optimization of runtime libraries.It discusses these key techniques in depth and analyzes pros and cons of some successful systems,before outlining future directions.
