JRockit JVM与HotSpot JVM [英] JRockit JVM versus HotSpot JVM

问题描述

如果有人能够提供关于两个JVM的优缺点的简要信息，因为它们都依赖于标准JVM规范。

If anyone can give me brief information about the advantages and disadvantages of the two JVM since they all depend on the Standard JVM Specification.

推荐答案

JRockit最初由Appeal和BEA Systems开发，然后被Oracle收购以运行服务器软件。 ¹ 它旨在针对需要长时间运行任务，大量内存和大量内存的大型应用程序进行优化。一个可扩展的环境，甚至比在服务器模式（另请参阅：&之间的真正差异; java -server"和java -client"？）。

JRockit was originally developed by Appeal and BEA Systems before being acquired by Oracle to run server software.¹ It was meant to be optimized for large applications requiring long running tasks, a lot of memory and a scalable environment, pushing optimizations for these scenarios even further than the Sun HotSpot JVM in server-mode (see also: Real differences between "java -server" and "java -client"?).

自Oracle收购Sun Microsystems以来，Oracle已经在使JRockit和HotSpot JVM融合的具体计划和路线图是两全其美的实现，主要建立在HotSpot上但是集成了JRockit最受欢迎的功能。

Since the acquisition of Sun Microsystems by Oracle, Oracle has communicated on a concrete plan and roadmap to have JRockit and the HotSpot JVM to converge to be a "best of both worlds" implementation, mostly built on HotSpot but integrating the most popular features of JRockit.

事实上，正如同一篇博客所述， JRockit将不会作为Java 7 JVM发布; JRockit的一些功能正在逐步引入HotSpot（内部甚至有时现在被称为HotRockit。

In fact, and as mentioned on the same blog, JRockit won't be released as a Java 7 JVM; and some of JRockit's features are being incrementally brought into HotSpot (internally even sometimes now referred to as "HotRockit").
