Linux Performance Tuning
Grand Ballroom C
The Linux operating system is commonly used both in the data center and for scientific computing applications; it is used in embedded systems as small as a wristwatch, as well as in large mainframes. As a result, the Linux system has many tuning knobs so that it can be optimized for a wide variety of workloads. Some tuning of the Linux operating system has been done ""out of the box"" by enterprise-optimized distributions, but there are still many opportunities for a system administrator to improve the performance of his or her workload on a Linux system.
This class will cover the tools that can be used to monitor and analyze a Linux system, and key tuning parameters to optimize Linux for specific server applications, covering the gamut from memory usage to filesystem and storage stacks, networking, and application tuning.
Intermediate and advanced Linux system administrators who want to understand their systems better and get the most out of them.
The ability to hone your Linux systems for the specific tasks they need to perform.
