About:
stress-ng is a powerful command-line tool designed to load and stress test computer subsystems including CPU, memory, I/O, and scheduler. It provides a comprehensive suite of over 280 different stress tests to exercise hardware and kernel capabilities under extreme conditions. The tool is invaluable for identifying system stability issues, thermal throttling, and performance bottlenecks.
Key Features:
  • Over 280 distinct stress methods for comprehensive testing
  • Fine-grained control over CPU, memory, I/O, and scheduler stress
  • Supports both single-threaded and multi-threaded stress testing
  • Detailed metrics and statistics for performance analysis
  • Configurable timeout and resource limits
Use Cases:
  • System stability and reliability testing for new hardware
  • Thermal and power consumption analysis under load
  • Performance benchmarking and bottleneck identification
  • Kernel and driver stress testing
Alternatives:
  • stress – Original stress tool with fewer stress methods and less configurability
  • stress-ng – stress-ng is the more modern and comprehensive version
