TuneD is a system tuning service for Linux. It applies collections of settings through named profiles, allowing a machine to be configured for different performance, latency, throughput and power-consumption requirements.
Profiles provide a reproducible way to describe system tuning policy instead of scattering individual adjustments across scripts and configuration files. They can also inherit settings from other profiles, making it easier to build specialized configurations without unnecessary duplication.
TuneD includes a daemon for continuous operation together with command-line and D-Bus interfaces. Its plug-in architecture allows profiles to control a wide range of kernel and device settings.
This is free and open source software.
Key Features
- Monitor connected hardware through the udev device manager.
- Apply groups of system settings through selectable tuning profiles.
- Configure sysctl, sysfs and kernel command-line parameters through a plug-in architecture.
- React to devices being added or removed while the daemon is running.
- Control TuneD from the command line with tuned-adm.
- Expose control functionality over D-Bus for integration with administration tools.
- Provide predefined profiles aimed at common workloads and hardware configurations.
- Allow custom profiles to inherit settings from other profiles.
- Support rollback so changes made by a profile can be reverted.
- Run in a reduced no-daemon mode where persistent monitoring is unnecessary.
- Show the active profile and information describing available profiles.
- Provide tuned-ppd as a compatibility service for applications using the power-profiles-daemon interface.
- Map power-saver, balanced and performance requests onto configurable TuneD profiles.
- Allow different power-profile mappings for AC and battery operation.
- Detect battery operation when selecting appropriate power-profile mappings.
