Overview

In this guide, we will explore Linux application and system performance analysis and learn how to find where a system is spending time. Annotating applications and finding performance bottlenecks helps focus software optimization efforts to improve system performance.

The Streamline Performance Analyzer provides system performance metrics, software tracing, and statistical profiling to help engineers get the most performance from hardware and find important bottlenecks in software.

The Raspberry Pi 3 and the Raspberry Pi 4 are low-cost boards with Cortex-A processors. This means that a Raspberry Pi is a useful tool for learning Linux profiling with Streamline. Because Raspberry Pi boards are designed for education, they do not require complex procedures to enable profiling features.

Before you begin

To work through this guide, you will need access to Streamline, which we will explain in Starting Streamline. You will also need a Raspberry Pi 3 or Raspberry Pi 4 board. An HDMI monitor and USB keyboard and mouse is the easiest way to interact with the Raspberry Pi. Finally, an SD card is needed to hold the Raspbian operating system.

A basic understanding of working with terminals in Linux will also be helpful.
