说明
tuned is a daemon that monitors system usage and dynamically adjusts system settings to optimize performance. It uses profiles that configure CPU governors, disk I/O schedulers, kernel parameters, and power management settings. The daemon can operate in static mode (applying fixed settings from a profile) or dynamic mode (adjusting settings based on real-time system activity). Profiles are stored in /etc/tuned/ and /usr/lib/tuned/. Management is done through tuned-adm, which communicates with the daemon to switch profiles and query status. Custom profiles can be created by extending existing ones or defining new tuning rules.
