From the Back Cover

• The first comprehensive, expert guide for end-to-end Linux application optimization
• Learn to choose the right tools—and use them together to solve real problems in real production environments

Superior application performance is more crucial than ever—and intoday’s complex production environments, it’s tougher to ensure, too.If you use Linux, you have extraordinary advantages: complete sourcecode access, plus an exceptional array of optimization tools. But thetools are scattered across the Internet. Many are poorly documented.And few experts know how to use them together to solve real problems.Now, one of those experts has written the definitive Linux tuningprimer for every professional: Optimizing Linux® Performance.
Renowned Linux benchmarking specialist Phillip Ezolt introduces eachof today’s most important Linux optimization tools, showing how theyfit into a proven methodology for perfecting overall applicationperformance. Using realistic examples, Ezolt shows developers how topinpoint exact lines of source code that are impacting performance. Heteaches sysadmins and application developers how to rapidly drill downto specific bottlenecks, so they can implement solutions more quickly.You’ll discover how to:

• Identify bottlenecks even if you’re not familiar with the underlying system
• Find and choose the right performance tools for any problem
• Recognize the meaning of the events you’re measuring
• Optimize system CPU, user CPU, memory, network I/O, and disk I/O—and understand their interrelationships
• Fix CPU-bound, latency-sensitive, and I/O-bound applications, through case studies you can easily adapt to your own environment

Install and use oprofile, the advanced systemwide profiler for Linux systems
If you’re new to tuning, Ezolt gives you a clear and practicalintroduction to all the principles and strategies you’ll need. Ifyou’re migrating to Linux, you’ll quickly master Linux equivalents tothe tools and techniques you already know. Whatever your background orenvironment, this book can help you improve the performance of all yourLinux applications—increasingbusiness value and user satisfaction atthe same time.
