For example Chapter 9 focuses on the topic of benchmarking multi-tiered applications and it even dares to touch the topic of Markov chains for modeling realistic interactions and therefore gathering useful synthetic data taking into account preformance fact that for most of the enterprise Java developers secondary school arithmetic is more than enough, this chapter can be easily considered as rocket science for the majority of Java developers.

If there are concerns about whether that performance can be met early in the software development process, then you have jaca luxury to mitigate that risk by conducting some experiments to identify whether those risks are “real” along with whether you cbarles need to make some alternative decisions, which may require a major shift in the choice of software architecture, design or implementation.

Granted, it doesn’t say much about how to write better java code.

Elsewhere the two profilers featured are the admittedly excellent Oracle Solaris Studio Performance Analyzer tool, and the NetBeans profiler. Thanks for telling us about the problem. However, we should let the data that’s collected drive the performance tuning effort. Leonid Igolnik rated it really liked it Dec 21, To ask other readers questions about Java Performanceplease sign up.


The two chapters covering profiling one focused on using Oracle’s Solaris Studio Performanec Analyzer and the NetBeans Profiler, and the other on resolving common issuesare also first-rate, and I was particularly pleased to find an appendix with source code examples for common, but hard to resolve, problems such as lock contention, performnce Java collections, and increasing parallelism.

One, what we’re trying to describe here is the notion of huntt an experiment” around the questions you want to have answered, or what you want to learn.

Also, we noticed there were folks who were using combinations of Java HotSpot VM command line options that just didn’t make sense.

humt The VM guessing what heap size to use isn’t ergonomic – it doesn’t really have human factors impact – unless you can get RSI from a poorly tuned VM. Can’t performnace I read it all. I would also have liked to have seen some discussion around alternative garbage collectors, such as Oracle’s JRockit, IBM’s Balanced GC which to be fair may have appeared to late for the book’s production schedule or Azul’s C4, which don’t get a mention.

Ajiknya Dhomne rated it it was amazing Nov 12, After all, they’re usually trying to solve similar problems. In addition, the section on writing effective benchmarks, and the sort of issues that a smart JIT compiler can cause, is very strong, showing you how you can take a look at the generated assembly code from the JIT compiler to make sure your microbenchmark is doing what you think it is doing. In addition, our hope is joyn readers will also question whether any other differences in their testing environment versus production may introduce some unexpected or unforeseen flaw s.

Java Concurrency in Practice. It depends on what you want to learn from the performance test and it also depends on how the environment deviates from the production environment. Over a million developers have joined DZone. It can also potentially be used or incorporated as part of an acceptance test plan with the users of the application. Chapter 9 shows how Little’s law could be used for benchmark validation.


The authors are very careful to explain concepts concretely by giving examples from Linux, Solaris and MS Windows systems, which makes sense given the portability of JVM. However, keep in mind that you need to be able to convince yourself, and your stakeholders, that the differences between your testing environment and the production environment do not introduce performance differences.

The book is particularly good on low level details, with the myriad of different HotSpot command line options well represented, and an excellent, step-by-step guide to JVM tuning.

Explore the Home Gift Guide. Finally, even though they provide detailed code listings which are used to indicate different techniques for performance anaylsis and profiling, they are not from real world scenarios and this artificial examples might not be very helpful for the majority of the developers apart from demonstration purposes.

By the way, there are times when it’s useful to understand why a given environment, setup, etc introduces wide variability between test runs, especially when you’re looking for small percentage improvements in performance, or you’re wanting to identify small percentage improvements in performance.
