GtkStressTesting, also known as GST, is a graphical utility for stressing and monitoring hardware components on Linux.
It provides a GTK frontend for stress-ng, making processor and memory stress tests accessible without constructing stress-ng commands manually. Alongside stress testing, GST displays a useful collection of processor, memory, motherboard and sensor information.
The application can therefore be used both to put hardware under sustained load and to watch how the system behaves while that load is applied.
This is free and open source software.
Key Features
- Runs CPU and memory stress tests through stress-ng.
- Provides single-core and multi-core benchmark modes.
- Displays processor model, core, thread, family and feature information.
- Shows processor cache information.
- Displays motherboard vendor, model and BIOS information.
- Reports RAM capacity, speed, rank, manufacturer and part information where available.
- Shows per-core and overall processor utilisation.
- Displays current memory usage.
- Monitors processor core clock frequencies.
- Reads hardware-monitoring information exposed through Linux hwmon interfaces.
- Provides a graphical interface suitable for monitoring a system while stress tests run.
