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.
