Introduction to Linux Performance Tuning

Course Summary

The Introduction to Linux Performance Tuning training course is designed to demonstrate how to tune a production system running Linux.

The course begins with an overview of performance methodologies, terminologies, and concepts. Next, it examines system levels and components like processes, threads, memory, disk I/o, and file systems. The course concludes with an exploration of OS specific tuning tools, like prstat on Solaris and strace on Linux.

Prerequisites: A fundamental background in Linux is expected, this builds off those foundations.
