Performance Tuning Management

Author: Usman O. Olanlanrewaju (Blu3 Sky)

Date: 2026/03/31

Focus: System tuning with tuned, profile management via tuned-adm, and applying recommended profiles for workload optimization

1. tuned — Dynamic System Tuning Daemon

tuned is a system tuning service that monitors storage, networking, processors, audio, video, and other connected devices, then adjusts their kernel parameters for better performance or power saving based on a chosen profile.

The management CLI is tuned-adm.

Component Location
Vendor profiles /usr/lib/tuned/profiles/
Custom profiles /etc/tuned/
Service unit tuned.service
Man pages man:tuned(8), man:tuned.conf(5), man:tuned-adm(8)

3. Profile Management

3.1 List all available profiles

$ sudo tuned-adm list
Available profiles:
- accelerator-performance     - Throughput performance based tuning with disabled higher latency STOP states
- aws                         - Optimize for aws ec2 instances
- balanced                    - General non-specialized tuned profile
- balanced-battery            - Balanced profile biased towards power savings changes for battery
- desktop                     - Optimize for the desktop use-case
- hpc-compute                 - Optimize for HPC compute workloads
- intel-sst                   - Configure for Intel Speed Select Base Frequency
- 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
- optimize-serial-console     - Optimize for serial console use.
- 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
Current active profile: virtual-guest

3.3 Check the currently active profile

$ tuned-adm active
Current active profile: virtual-guest

3.4 Get a profile recommendation for the system

tuned-adm recommend detects the environment (bare metal, VM, container) and suggests the most appropriate profile

$ tuned-adm recommend
virtual-guest

3.5 Switch to a different profile

$ tuned-adm profile balanced-battery

Profile changes take effect immediately — no reboot required.

3.6 Disable tuning entirely, then restore recommended profile

$ sudo tuned-adm off ;tuned-adm active;  sudo tuned-adm profile virtual-guest ; sudo tuned-adm active
No current active profile.
Current active profile: virtual-guest

tuned-adm off deactivates all tuning. Kernel parameters revert to their defaults. Always restore a profile before leaving a system unattended.
