Course Overview
Keeping your Linux systems running optimally is a mission-critical function for most Linux IT professionals. This course will teach you the appropriate tools, subsystems, and techniques you need to get the best possible performance out of Linux.
What you’ll learn
In this course students will learn about industry configuration best practices, the best tried-and-true optimization performance tuning tools and techniques, how to manually optimize the kernel’s behavior, tracing, profiling, and instrumentation techniques across a wide range of conditions, and more. This Linux performance optimization course prepares you to use all the tools and techniques you need to keep your Linux systems running at optimal levels. These techniques and tools have been developed and tested in the most demanding high-performance computing environments.
Requirements
- Students should be experienced Linux users. Familiarity with local system administration concepts covered in LFS301 Linux System Administration is required.
Target audiences
- This course is primarily intended for system administrators and technology architects who need to select and tune their environment to maximize speed and efficiency. This course is designed for IT professionals who are responsible for optimizing Linux performance.
