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.

Audience

This course is primarily intended for system administrators and technology architects who need to select and tune their environment to maximize speed and efficiency. Students should be experienced Linux users. Familiarity with local system administration concepts covered in LFS220 Linux System Administration is required.
