Linux Performance Tuning

Linux Performance Tuning Training

The Linux performance tuning course is intended for system administrators and technology architects who need to select and tune their environment to maximize speed and efficiency. This course is designed to give you 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.

It will cover:

  • 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.

This course is designed to work with a wide range of Linux distributions, so you will be able to apply these concepts regardless of your distro.

Contact us to book your seat. Training may be done on-site or at our training venues in Durban, Cape Town and Johannesburg.
