Dave Dagastine (Cobleskill, NY), Java SE Performance Engineering tech lead is actively involved in developing Java benchmarks at SPEC. Paul Hohensee (Nashua, NH) is Senior Staff Engineer for Sun Microsystems in Burlington, MA.
“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 the Java Programming Language
Improvements in the Java platform and new multicore/multiprocessor hardware have made it possible to dramatically improve the performance and scalability of Java software.
Java™ Performance covers the latest Oracle and third-party tools for monitoring and measuring performance on a wide variety of hardware architectures and operating systems. 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 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 Java HotSpot VM, standard and multitiered applications; Web applications, 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 Oracle Solaris environments
- Using modern Java Virtual Machine (JVM) and OS observability tools to profile running systems, with almost no performance penalty
- Gaining “under the hood” knowledge of the Java 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 Java 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 Java 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.

Essential information hard-to-find anywhere else, By
This review is from: Java Performance (Paperback)
This is an outstanding book and one of the few that, even after working through, I'll be keeping within reach at my desk. After almost a decade working on the JVM, I've only recently begun work on some software that really strains our systems, processing a million and some records a day with several instances each on multiple threads, and so until recently, performance has always been a secondary concern. While the app's code is certainly not perfect, I started wondering whether any of the mysterious extended options available to the JVM might take some of the weight off the system without having to wait until the next formal development/release cycle. This is what prompted me to look at this book, but as I'll describe, I found much more.I was very impressed with the amount of information provided: unlike most computer-related books, this is dense with text, rather than long code samples, screenshots and diagrams. Why is this a good thing? This is not just a book on how to... Read more

lacks supportive data to corroborate the theories, By
This review is from: Java Performance (Paperback)
This book is essentially a compilation of all internal product documentations and freely available online tutorials without good examples to corroborate the theories presented throughout the book. It discusses JVM tuning as an infinite set of variables, which look more like infinite variety and challenges to the reader than anything concrete and useful. It is an "okay" book if you just want to "read" about Java performance, but if you have a real project and a real Java performance issue to deal with, you'll have to try out all the permutations and find out yourself which ones are helpful and which ones are not - only if you have infinite amount of time to do so. In reality, sometimes we just want to get a Java performance issue resolved as quickly as possible so that we can move on to the next task on our busy agenda. This book has clearly failed to meet the basic criterion of being data-driven to be a practical, useful guide to helping readers resolve their Java performance issues...

Good, but rather Oracle Centric,
This review is from: Java Performance (Paperback)
The last book to cover this topic n any detail was Steve Wilson et al's "Java Platform Performance", which was published in 2000. HotSpot has moved on a fair bit since then, so its good to see a new book covering the subject.The sections on JVM tuning and profiling are particularly strong. There's also a decent section on HotSpot Garbage Collectors, though I would have liked to see some more discussion on alternative GC algorithms such as IBM's Balanced Garbage Collector and Azul's C4. It should be noted that there is a definite bias towards Oracle's tools and hardware. For example the section on "Choosing the Right CPU architecture" concentrated mainly on Oracle's SPARC chips. Also the two profilers featured are the Oracle Solaris Studio Performance Analysiser Tool, and the NetBeans profiler. Likewise in the Java EE Section all the examples are based on Glassfish. The book doesn't provide a recipe for solving every problem, but does provide... Read more |
