Perfect various performance book for standard java developers

Perfect various java performance book. Standard performance books are all about GC, JVM, classloaders and the stuff, but this book touches different aspects of java performance avoiding too detailed information that is for sure not important for java programmers excluding oracle JVM developers or HFT systems developers who really need to know all JVM insides. Though this does not seem that all themes are covered superficially they are really valuable and useful. GC advice helped me in production very much.Style of book is light, examples are clear, I think every java developer should read this book for sure

Excellent insight into the working of the JVM and the GC in particular.

The starting discussion on general performance optimization is not very useful for an experienced programmer. For example the advice to "write better algorithms" is not really what I was looking for in a book on Java performance. However, for inexperienced programmers it is a good starting place.For those looking for Java specifics the later chapters contain the most useful information. Of primary interest was the discussion of the inner working of the GC, the JIT and the heap. The hints and special cases were useful guidelines and provided information on areas to start looking for optimization but were of less overall utility than the JVM discussions.

I've already used it with great benefit on the application I work with

An outstanding resource that lives up to its title. Oaks is expert and gives clear descriptions of how to measure and understand Java performance, why it works as it does, and the steps the practitioner should take to improve performance. I've already used it with great benefit on the application I work with. The strongest possible recommendation for anybody working with Java.

It gives you all possible JVM settings for you tweak and try extract the better performance from your environment

I hand't finished the book yet though so far it has impressed me. It gives you all possible JVM settings for you tweak and try extract the better performance from your environment, the thing that hook me up is that it use a recent JDK version.

Generally a nice book and a good thing to use as references though I guess JVM documentation can do the same thing. The take-out of this book is that it can guide you into situation when you might want to think about some JVM param tuning. The author is also quite honest in his writing at the beginning. The best and most applicable way to improve software performance is at the algorithm and coding level.Some readers here may dissect his examples further, but I think the author has already cautioned us at the beginning about the gain from tuning JVM parameters. Defaults JVM parameters will be good in the vast majority of cases. Overall, I would like to give a 3.5, but since I can't do that. I think 3 is a fair score.

Really love this. Its like a novel to read and he lays out clearly how each of the things will affect the performance. I upgraded the performance of my app from 67K to 193K messages/second. I am really interested in connecting with him in LinkedIn.

Great guide to JVM and Java performance

Overall this book has given an amazing insight into JVM performance tuning and considerations regarding Java SE code performance.However I found the JEE part was lacking in detail in comparison to the other parts.

Just like the title says

Just like the title says, it's really THE definitive guide. A complete guide, covering in a bright way most of the content about Java and HotSpot JVM Performance Engineering.
