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.
