T is freely available Apart from that authors are a little biased towards Oracle eg mentioning only NetBeans and Solaris Studio Performance Anaylzer without touching on Eclipse Finally even though they provide detailed code listings which are used to indicate different techniues for performance anaylsis and profiling they are not from real world scenarios and this artificial examples might not be very elpful for the majority of the developers apart from demonstration purposesConclusion I can wholeheartedly recommend this book to any software engineer who wants to understand the Java platform and Java Virtual Machine from a performance perspective as well as to engineers who want to tune their applications for better performance I sat in "an airport reading this for uite a while as some guy next to me sat talking on Frankenstein; or The Modern Prometheus his phoneelping people "airport reading this for uite a while as some guy next to me sat talking on Geometry Part 1: Quickstudy Laminated Reference Guide (Quick Study Academic) his phoneelping people Linux servers Clearly an extrovert Herbier et autres collections he kept talking to random people even betweenis phone calls When Historical Archaeology: Why the Past Matters he finally finishede asked me about the novel I was reading I laughed at The Happiest Baby on the Block howe called it a novel the plot was thin and characterization left a lot to be desired but in the end Blu oltre la prua: Un'avventura di Jack Aubrey e Stephen Maturin - Master Commander (La Gaja scienza Vol. 946) he laughedarder in some circles the two words Java and Performance are considered contradictionsThis is not a book about code algorithms or even programming It s about tuning It s about using freely available tools to diagnose problems like lock contention memory swapping or disk usage It s about understanding Releasing Heaven on Earth: Gods Principles for Restoring the Land how your CPU architecture impacts the performance of your application It s about understanding what goes on in the background in the Java virtual machine like garbage collection just in time compilation decompilation and re optimization and other stuff that you might not know is going on It s aboutow to monitor or ultimately profile your application to diagnose problems It s about The Future of English Teaching Worldwide how to optimize the memorylatencythroughput tradeoffs It s aboutow to set up benchmarks to accurately measure differences in performance It s about Between how to get the best throughput in a service oriented architectureIn other words this is a lot useful than a bag of coding tricks to make your program work better A knowledge and understanding of the workings of the JVM can be useful andopefully interesting to anyone who works on moderate to complex Java applications While I would recommend the first few chapters to any developer this is most useful for those who need to sueeze the most out of their systems with strict memory or latency reuirements or a need to maximize the responsiveness of their system.

Ers 5 and 6 focus on profiling which makes sense because you cannot improve something if you can t measure it carefully After introducing the fundamental concepts about profiling the authors give concrete examples using different profilers such as Oracle Solaris Studio Performance Anaylzer and NetBeans profilerChapter 7 can be considered the most critical part of the book Authors dedicate 70 pages to a detailed discussion on tuning the JVM and the various garbage collectors They refrain from making bold statements and always stress ow these things are very context sensitive and without proper measurement and profiling not many things can be generalized They The Happiness Secrets Of Joel Osteen have my utmost respect for this scientific and engineering approachChapter 8 Benchmarking Java Applications is where the scientific approach is taken to its full potential The authors explainow to construct Seashells hypotheses regarding performance problemsow to conduct experiments to gather data from the
