Summary

Java® Performance Companion shows how to systematically and proactively improve Java performance with today’s advanced multicore hardware and complex operating system environments.

The authors, who are all leading Java performance and Java HotSpot VM experts, help you improve performance by using modern software engineering practices, avoiding common mistakes, and applying tips and tricks gleaned from years of real-world experience.

Picking up where Charlie Hunt and Binu John’s classic Java Performance left off, this book provides unprecedented detail on two powerful Java platform innovations: the Garbage First (G1) garbage collector and the HotSpot VM Serviceability Agent.

Coverage includes

• Leveraging G1 to overcome limitations in parallel, serial, and CMS garbage collection
• Understanding each stage of G1 GC collections, both young and old
• Getting under the hood with G1 and efficiently fine-tuning it for your application
• Identifying potential optimizations, interpreting experimental results, and taking action
• Exploring the internals of the HotSpot VM
• Using HotSpot VM Serviceability Agent to analyze, triage, and resolve diverse HotSpot VM issues
• Troubleshooting out of memory errors, Java level deadlocks, and HotSpot VM crashes
• Extending the Serviceability Agent, and using the Plugin for VisualVM
• Mastering useful HotSpot VM command line options not covered in Java™ Performance

Java® Performance Companion can help you squeeze maximum performance and value from Java with JDK 8 or 9–for any application, in any environment.

Author Biography

Charles J. Hunt, Java performance engineer at Oracle, works to improve the performance of Java SE (Standard Edition), Java EE, the Java HotSpot VM, and the Java SE class libraries. He speaks regularly on Java performance at events including JavaOne, QCon, Velocity, and Dreamforce; and actively participates in open source communities including Project Grizzly (as a co-project owner and contributor). Hunt co-authored Java Performance and NetBeans IDE Field Guide. He wrote his first Java application in 1998, joined Sun Microsystems in 1999 as Senior Java Architect, and has focused on Java performance ever since. As Architect of Performance Engineering at Salesforce.com, he was responsible for improving the performance of Salesforce.com's infrastructure, mobile, and UI. Poonam Bajaj (Bengaluru Area, India) is Principal Member of Technical Staff at Oracle. She was previously Staff Engineer at Sun Microsystems, and Software Engineer at Satyam Computer Services Ltd. Bengt Rutisson, Member of the HotSpot Group, has worked on HotSpot garbage collection for five years, and contributed 100+ changes to OpenJDK, including significant performance improvements. As Development Manager at Oracle, he specialized in JRockit garbage collection and memory management. Monica Beckwith (Austin, TX Area), Java Performance Architect at Servergy, helps to build hyper-efficient servers that reduce energy, cooling, space, weight, water and carbon footprint by 80% or more. She led Oracle's Garbage First Garbage Collector performance team, and was named a JavaOne 2013 Rock Star. John Cuthbertson (San Francisco Bay Area, CA) is Senior Software Engineer at Azul Systems. He has served as software engineer or staff engineer at Oracle (specializing in the Hotspot Java VM); at HP, Intel, and at Edinburgh Portable Compilers. He was named a JavaOne 2013 Rock Star.
