# ColinIanKing/stress-ng

This is the stress-ng upstream project git repository.  stress-ng will stress test a computer system in various selectable ways. It was designed to exercise various physical subsystems of a computer as well as the various operating system kernel interfaces.

## What it is
stress-ng is a command-line stress testing tool with 380+ stressors that exercise CPU, memory, filesystem, and OS kernel interfaces. It is designed to trip hardware issues like thermal overruns and expose operating system bugs under heavy load.

## Use cases
- stress test cpu memory and disk on a linux server
- trip thermal overruns to find hardware issues
- exercise kernel interfaces under heavy system load
- measure throughput changes across os releases or hardware
- soak test a machine before deployment
- reproduce system bugs that only occur under load

## When to choose
- you need to load-test physical subsystems or kernel interfaces on POSIX systems
- you want a portable stress tool across Linux, BSDs, macOS, and many CPU architectures
- you need rough throughput measurements to compare hardware or OS versions

## When to avoid
- you need a precise, reproducible benchmark suite - stress-ng explicitly is not one
- you cannot tolerate a system running hot or thrashing, as some stressors can destabilize hardware
- you need GUI-based system testing

## Facets
- artifact type: cli-tool
- maturity: active
- function: testing, benchmarking, developer-tools
- domain: developer-tools, operating-systems, performance, testing
