Paperback. Pro PHP Application Performance will help you understand all the technologies and components which play a role in how well your applications run. When seconds can mean the difference between retaining a user and losing a user, it's important for all of us to have optimization as part of our project roadmap. But what components within your application should you analyze? How should you optimize? And how can you measure how well your application is performing? These are some of the questions that are answered in this book. Along the way you will also learn the "why" of optimizing. Youll discover why you should optimize a specific component, why selecting one function over another is beneficial, and how to find and use the optimization tools available to the open source community. Youll also learn how to deploy caching software as well as web server software. Pro PHP Application Performance will also teach you more advanced techniques, such as: Using Xdebug to profile functions that are not running as efficiently as possible. Comparing opcode executed by different PHP functions to narrow the search for functions that run efficiently. Using strace to analyze Apache while your application is served to the user. Once you complete this book you will have a complete sense of where to start optimizing and, most importantly, have the tools which allow you to continue optimizing in other PHP applications going forward. Pro PHP Application Performance will also teach you more advanced techniques, such as: Using Xdebug to profile functions that are not running as efficiently as possible.

Riassunto

This book contains tips, tricks, and techniques to make new and existing PHP applications much faster and less resource-hungry. Author Armando Padilla looks at all major sections of the PHP application stack-from server hardware to database and web server performance. PHP program application performance is the center of this book, and Padilla shows you how to improve performance by best practices, proper design, and best-of-breed tools. Padilla starts out by establishing performance testing and benchmarking methodology using common open source and browser-based testing tools. He then discusses best practices for PHP development, and also explains refactoring existing code, both with performance in mind. In addition to best coding practices, this book will teach you how to use and tweak Opcode caches such as APC, XCache, and eAccelerator. Padilla then highlights how to support the efficient running of PHP applications, tweaks and settings by taking advantage of the GNU/Linux and Microsoft Windows operating systems to improve hosting performance and reliability. Additional tips on web server improvements and database administration help round out the picture. Finally, Padilla presents some hardware example configurations tuned for high performance. What you'll learn How to improve the performance of existing PHP applications How to maximize the performance of existing operating systems and databases How to refactor existing PHP code for better performance How to identify and rectify bottlenecks in PHP code How to take advantage of variable caching to increase performance Strategies for selecting server hardware for best performance Who this book is for This books will appeal to established PHP developers who wish to write new, complex applications or want to rearchitect existing ones. Developers of other languages such as Ruby, Python, and VB.NET will also have an interest in the techniques for tuning the performan
