Oracle JRockit: The Definitive Guide

Overview of this book

Oracle JRockit is one of the industry’s highest performing Java Virtual Machines. Java developers are always on the lookout for better ways to analyze application behavior and gain performance. As we all know, this is not as easy as it looks. Welcome to JRockit: The Definitive Guide.This book helps you gain in-depth knowledge of Java from the JVM’s point of view. We will explain how to write code that works well with the JVM to gain performance and scalability. Starting with the inner workings of the JRockit JVM and finishing with a thorough walkthrough of the tools in the JRockit Mission Control suite, this book is for anyone who wants to know more about how the JVM executes your Java application and how to profile for better performance.

Industry-standard benchmarks


The industry and the academic community continuously strive to provide generic benchmarks that emulate many common programmatic problems for Java. This is, of course, is of interest to JVM vendors and hardware vendors (to make sure that the JVM itself performs well and also for marketing purposes). However, the standardized benchmarks often provide some insights on tuning the JVM for a specific problem. It is recommended to have a look at some of the things that the industry tries to benchmark in order to understand how Java can be applied to different problem domains.

Naturally, standard benchmarks for anything and everything exists. Many software stacks are subject to performance measurement standardization, with organizations releasing benchmarks for everything from application servers down to network libraries. Finding and using industry-standard benchmarks is a relevant exercise for the modern Java developer.
