Troubleshoot the most widespread and pernicious Java performance problems using a set of open-source and freely-available tools that will make you dramatically more productive in finding the root causes of slow performance. This is a brief book that focuses on a small number of performance anti-patterns, and you’ll find that most problems you encounter fit into one of these anti-patterns. The book provides a specific method in a series of steps referred to as the “P.A.t.h. Checklist” that encompasses persistence, alien systems, threads, and heap management. These steps guide you through a troubleshooting process that is repeatable, that you can apply to any performance problem in a Java application. This technique is especially helpful in 'dark' environments with little monitoring. Performance problems are not always localized to Java, but often fall into the realms of database access and server load. This book gives attention to both of these issues through examples showing how to identify repetitive SQL, and identify architecture-wide performance problems ahead of production rollout. Learn how to apply load like an expert, and determine how much load to apply to determine whether your system scales. Included are walk-throughs of a dozen server-side performance puzzles that are ready to run on your own machine. Following these examples helps you learn to: Assess the performance health of four main problems areas in a Java system: The P.A.t.h. Checklist presents each area with its own set of plug-it-in-now tools Pinpoint the code at fault for CPU and other bottlenecks without a Java profiler Find memory leaks in just minutes using heapSpank, the author's open-source leak detector utility that is freely available from heapSpank.org The repeatable method provided in this book is an antidote to lackluster average response times that are multi-second throughout the industry. This book provides a long absent, easy-to-follow, performance training regimen that will benefit anyone programming in Java. What You'll Learn Avoid the 6 most common ways to mess up a load test Determine the exact number of threads to dial into the load generator to test your system's scalability Detect the three most common SQL performance anti-patterns Measure network response times of calls to back-end systems ('alien systems') Identify whether garbage collection performance is healthy or unhealthy and whether delays are caused by problems in the old or new generation, so you know which generation needs to be adjusted Who This Book Is For Intermediate and expert Java developers and architects. Java experts will be able to update their skill set with the latest and most productive, open-source Java performance tools. Intermediate Java developers are exposed to the most common performance defects that repeatedly show up in Java applications, ones that account for the bulk of slow-performing systems. Experts and intermediates alike will benefit from the chapters on load generation.

Inhaltsangabe:Introduction: Despite the widespread recognition that performance is important to the success of a project, many software products fail to respond fast enough to user requests or to handle a certain amount of parallel business transactions. This is because nowadays projects are result-oriented where the focus is on functionality to be implemented. Such projects do not pay high attention to application performance because it still does not have the particular importance that unit testing for example has. Moreover today s development models usually consider performance management only in a limited way within their lifecycle and often follow what is known as the fix it later approach. The fix it later approach concentrates on software correctness and defers performance considerations to the integration testing phase where additional hardware is added or a system is tuned when performance issues are detected. The problem of neglecting performance management is that performance issues often do not emerge until an application is put into production, where it is likely to suffer the consequences of a performance failure. The consequences of performance failures can be increased operational costs, increased development and hardware costs, and damaged customer relations. If severe performance issues are discovered during production, it may be too expensive to re-design a system or even impossible to add additional hardware in order to meet performance objectives. Such projects are likely to be canceled and their costs will be unrecoverable. To avoid such situations, performance management should be integrated into an application s lifecycle from the beginning. This means that performance objectives have to be defined early within a project and continually verified as an application evolves. Having performance management integrated from the beginning allows to reduce overall project risk and costs because performance issues can be spotted and corrected early in the lifecycle and even before end users are affected. Furthermore an application is extensively tested for its ability of reaching performance objectives before it is deployed to a production environment and exposed to real users.

The objective of APM Best Practices: Realizing Application Performance Management is to establish reliable application performance management (APM) practices—to demonstrate value, to do it quickly, and to adapt to the client circumstances. It's important to balance long-term goals with short-term deliverables, but without compromising usefulness or correctness. The successful strategy is to establish a few reasonable goals, achieve them quickly, and then iterate over the same topics two more times, with each successive iteration expanding the skills and capabilities of the APM team. This strategy is referred to as “Good, Better, Best”. The application performance monitoring marketplace is very focused on ease of installation, rapid time to usefulness, and overall ease of use. But these worthy platitudes do not really address the application performance management processes that ensure that you will deploy effectively, synergize on quality assurance test plans, triage accurately, and encourage collaboration across the application life cycle that ultimately lowers overall application cost and ensures a quality user experience. These are also fine platitudes but these are the ones that are of interest to your application sponsors. These are the ones for which you need to show value. This CA Press book employs this iterative approach, adapted pragmatically for the realities of your organizational and operational constraints, to realize a future state that your sponsors will find useful, predictable and manageable—and something that they will want to fund. In the meantime, you will learn the useful techniques needed to set up and maintain a useful performance management system utilizing best practices regardless of the software provider(s).
