Performance Tuning for Linux Servers

An indispensable guide to maximizing Linux system and application performance. From Wall Street to Hollywood, Linux runs many of the world's most business critical 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 Servers will help you maximize the performance and value of every Linuxsystem and application you run.An indispensable guide to maximizing Linux system and application performance.
