基于Soot的JAVA字节码优化及性能分析

Java语言至今已成为最受欢迎的编程语言之一,由于其平台无关性、执行的安全性以及垃圾收集等特性而得到广泛应用,受到众多的IT企业及开发者的支持。然而,与诸如C/C++这类语言比起来,Java语言的运行性能在很多情况下还有待提高,优化Java应用性能的课题就成为当前业界迫切需要解决的问题和研究的热点。本文从优化Java字节码的角度切入,介绍一款在其上进行优化和变换的框架,并展示相关应用的例子。

JAVA By Tecode Optimization and Performance Analysis Based on Soot

Java has become one of the most popular programming languages and well supported by numerous IT enterprises and developers, due to its many features like platform -independence, execution security and garbage collection. However, as to C and C ＋＋ , the execution speed of Java needed much further improvement and the issue of optimizing Java applications has been evolving a hotspot in the industry. The paper discusses Java bytecode optimization technique along with an optimization and transformation framework called Soot, and presents some examples used on optimization issues.
