Performance tuning and capacity planning for Red Hat Enterprise Linux

Red Hat® Enterprise Performance Tuning teaches senior Linux® system administrators about performance tuning for Red Hat Enterprise Linux.

Course Overview

This course discusses system architecture with emphasis on:

  • Understanding the implications on system performance
  • Methods for testing the effects of performance adjustments
  • Open source benchmarking utilities
  • Methods for analyzing system and networking performance
  • Tuning configurations for specific application loads

This course can also help you prepare for the Red Hat Certificate of Expertise in Performance Tuning exam (EX442).


Target Audience:

Experienced Linux system administrators responsible for maximizing resource utilization through performance tuning.
An RHCE interested in earning a Red Hat Certification of Expertise, or an Red Hat Certified Architect (RHCA).

Delegates will learn how to

Course content summary

  • Tuning for use-case scenarios (for example, HPC, large memory, database, and file server)
  • Applying tuning profiles with tuned
  • Tuning virtual machines (primarily guest, but host is discussed)
  • Tuning memory and caches
  • Tuning CPU and memory utilization using cgroups (integrated in systemd)
  • Gathering performance metrics and other data for tuning purposes

Impact on the organization

This course is intended to develop the skills needed to improve infrastructure performance, increase system utilization, reduce downtime, and improve responsiveness to system failures.

Red Hat has created this course in a way intended to benefit our customers, but each company and infrastructure is unique, and actual results or benefits may vary.

Impact on the individual

As a result of attending this course, students should be able to obtain, analyze, and interpret system performance metrics, which the business can use to increase cost effectiveness, maximize application performance, and make better decisions about investment in hardware or cloud resources.

Students should be able to demonstrate the following skills:

  • Describe how key Linux subsystems work
  • Interact with applications
  • Determine which tuning adjustments are relevant in different situations
