Java Performance

Ve>“The definitive master class in performance tuning Java applications& if you love all the gory details, this is the book for you.� –James Gosling, creator of Java Improvements in the Java platform and new multicore/multiprocessor hardware have made it possible to dramatically improve the performance and scalability of Java software. Now, two leading Java performance experts have written the first start-to-finish guide to optimizing Java performance in today’s systems. Writing for developers, designers, and architects, Charlie Hunt and Binu John offer uniquely detailed, comprehensive, and up-to-date coverage of all aspects of Java performance improvement, from monitoring and profiling to upgrading code from Java 1.4.2 or Java 5. Java" Performancecovers the latest Oracle and third-party tools to monitor and measure performance on a wide variety of hardware architectures and operating systems. Drawing on their unsurpassed insider experience, the authors present dozens of tips and tricks you’ll find nowhere else. You’ll learn how to construct experiments that identify opportunities for optimization, interpret the results, and take effective action. You’ll also find powerful new insights into microbenchmarking–including how to avoid common mistakes that can mislead you into writing poorly performing software. Then, building on this foundation, you’ll walk through optimizing the Oracle HotSpot VM; standard and multitiered applications; Web applications and services; persistence, EJBs, and more. Coverage includes: Taking a proactive approach to meeting application performance and scalability goals Monitoring Java performance at the OS level in Windows, Linux, and Solaris environments Using modern JVM and OS observability tools to profile running systems, with almost no performance penalty Gaining “under the hood� knowledge of the Oracle HotSpot VM that can help you address most Java performance issues Integrating JVM-level and application monitoring Mastering Java method and heap (memory) profiling Tuning the Oracle HotSpot VM for startup, memory footprint, response time, and latency Determining when Java applications require rework to meet performance goals Systematically profiling and tuning performance in both Java SE and Java EE applications Optimizing the performance of the Oracle HotSpot VM Using this book, you can squeeze maximum performance and value from all your Java applications–no matter how complex they are, what platforms they’re running on, or how long you’ve been running them.

Charlie Hunt is the JVM performance lead engineer at Oracle. He is responsible for improving the performance of the HotSpot JVM and Java SE class libraries. He has also been involved in improving the performance of the Oracle GlassFish and Oracle WebLogic Server. A regular JavaOne speaker on Java performance, he also coauthored NetBeans™ IDE Field Guide (Prentice Hall, 2005).

Binu John is a senior performance engineer at Ning, Inc., where he focuses on improving the performance and scalability of the Ning platform to support millions of page views per month. Before that, he spent more than a decade working on Java-related performance issues at Sun Microsystems, where he served on Sun’s Enterprise Java Performance team. John has contributed to developing industry standard benchmarks such as SPECjms2007 and SPECJAppServer2010; published several performance whitepapers; and contributed to java.net’s XMLTest and WSTest benchmark projects.
