Product Description

Linux Server Performance Tuning provides the knowledge and skills needed to understand and improve the performance of Linux servers. It describes the collective practical experience of IBM Linux Technology Center experts in Linux performance monitoring, evaluation and measurement, analysis, and tuning of Linux servers. It discusses methodologies for improving and maximizing the performance of business server applications running on an Intel-based hardware platform and the Linux operating system. Readers will obtains valuable insight into the tuning techniques needed to improve the performance of their software running on Linux. This includes an overview of the Linux kernel (including installation), a synopsis of the various Linux performance tools that can be used to isolate performance issues, and how to use them, and tuning principles, strategies and techniques for various Linux components such as the scheduler, memory and I/O subsystems. In addition, case studies for tuning these subsystems are also included, as well as the performance characterization of several Linux server applications, including web servers, database servers, application servers, and print and file servers.

From the Back Cover

• Proven techniques for optimizing web, file, print, database, and application servers
• Practical introductions to open source performance management tools
• Easy-to-understand examples based on Red Hat Enterprise Linux and Novell SUSE Linux Enterprise Server

An indispensable guide to maximizing Linux system and application performance

From Wall Street to Hollywood, Linux runs many of the world’s most businesscritical systems. Linux performance now impacts the entire enterprise. In Performance Tuning for Linux Servers, a team of IBM’s most-experienced Linux performance specialists shows you how to find bottlenecks, measure performance, and identify effective optimizations.

This book doesn’t just cover kernel tuning: it shows how to maximize the end-to-end performance of real-world applications and databases running on Linux. Throughout, the authors present realistic examples based on today’s most popular enterprise Linux platforms, Intel-based Red Hat Enterprise Linux, and Novell SUSE Linux Enterprise Server. These examples are designed for simplicity, clarity, and easy adaptation to any contemporary Linux environment. You’ll discover how to

• Install and configure Linux for maximum performance from the outset
• Evaluate and choose the right hardware architecture for your Linux environment
• Understand Linux kernels 2.4 through 2.6: components, performance issues, and optimization opportunities
• Master core Linux performance tuning principles and strategies
• Utilize free, open source tools for measurement, monitoring, system tracing, and benchmarking
• Interpret performance data to analyze your Linux server’s real-world behavior
• Optimize Linux system schedulers, memory, I/O, file systems, and networking
• Tune web, file, database, and application servers running commercial workloads
• Predict the impact of changes in tuning parameters or configurations
• Tune Linux code: optimize design, timing, sockets, threads, synchronization, and more
• Architect for maximum performance: SMP scaling, clustering, and topology
• Integrate kernel and application tuning in end-to-end system optimization projects

Whether you’re an administrator, developer, integrator, or consultant, Performance Tuning for Linux Serverswill help you maximize the performance and value of every Linux system and application you run.
