背景
Tuned is a system tuning service for Linux. It:
- monitors connected devices using the udev device manager
- tunes system settings according to a selected profile
- supports various types of configuration like sysctl, sysfs, or kernel boot command line parameters, which are integrated in a plug-in architecture
- supports hot plugging of devices and can be controlled from the command line or through D-Bus, so it can be easily integrated into existing administering solutions: for example, with Cockpit
- can be run in no-daemon mode with limited functionality (for example, no support for D-Bus, udev, tuning of newly created processes, and so on) for systems with reduced resources
- stores all its configuration cleanly in one place – in the Tuned profile – instead of having configuration on multiple places and in custom scripts

Available profiles:
- balanced - General non-specialized tuned profile
- desktop - Optimize for the desktop use-case
- hpc-compute - Optimize for HPC compute workloads
- latency-performance - Optimize for deterministic performance at the cost of increased power consumption
- network-latency - Optimize for deterministic performance at the cost of increased power consumption, focused on low latency network performance
- network-throughput - Optimize for streaming network throughput, generally only necessary on older CPUs or 40G+ networks
- powersave - Optimize for low power consumption
- throughput-performance - Broadly applicable tuning that provides excellent performance across a variety of common server workloads
- virtual-guest - Optimize for running inside a virtual guest
- virtual-host - Optimize for running KVM guests
