Tuned: Open Source Performance Profiling and Tuning for Linux

Discover the optimized performance and power management of Tuned, an open source performance profiling and tuning daemon for Linux, designed to maximize system performance and savings.

What is Tuned?

Tuned is an open source performance profiling and tuning daemon for Linux operating systems. It optimizes system settings dynamically based on detected workload characteristics to maximize performance and power savings.

Some key features of Tuned include:

• Profile-based tuning that optimizes settings based on whether the workload is throughput-oriented, latency-sensitive, power-savings focused etc.
• Dynamic tuning of CPU and storage devices to match real-time demands
• Integration with systemd for automatic profile activation and tuning on boot
• Plugin architecture that enables tuning different subsystems like CPU, kernel, networking, storage etc.
• Power savings capabilities like integrating with CPU idle states, disk idling etc.

Tuned can help improve performance substantially for workloads like database servers, web applications, file servers etc. while also enabling energy savings when systems are idle. It is included by default in many Linux distributions like Red Hat Enterprise Linux, CentOS, Fedora etc.
