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 in today's complex production environments, it's tougher to ensure, too. If you use Linux, you have extraordinary advantages: complete source code access, plus an exceptional array of optimization tools. But the tools 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 tuning primer for every professional: Optimizing Linux® Performance.
Renowned Linux benchmarking specialist Phillip Ezolt introduces each of today's most important Linux optimization tools, showing how they fit into a proven methodology for perfecting overall application performance. Using realistic examples, Ezolt shows developers how to pinpoint exact lines of source code that are impacting performance. He teaches sysadmins and application developers how to rapidly drill down to 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 practical introduction to all the principles and strategies you'll need. If you're migrating to Linux, you'll quickly master Linux equivalents to the tools and techniques you already know. Whatever your background or environment, this book can help you improve the performance of all your Linux applications—increasingbusiness value and user satisfaction at the same time.
