Red Hat Enterprise Performance Tuning (RH 442)

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

Target Audience

Senior Linux system administrators responsible for maximizing resource utilization through performance tuning.

Prerequisites

  • Red Hat Certified Engineer (RHCE) certification or equivalent experience
  • Candidates who have not earned their RHCE can confirm they have the correct skills by passing our online skills assessment

Course Objectives

  • 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
