summary

Tuned is a profile-driven system tuning service that applies, verifies and can roll back kernel and userspace settings for workloads like SAP, Oracle, DB servers or low-latency desktops. Profiles live in /etc/tuned or the package and can include plugin rules for disks, CPU isolation and bootloader edits; profiles auto-detect hardware and select themselves. Control is via tuned-adm profile <name> or D-Bus (Cockpit/Ansible integrations exist) and you can check differences with tuned-adm verify. Dynamic plugins adjust settings at runtime.
