Listing the available tuning profiles
[root@server ~]# 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
List the currently active tuning profile
[root@server ~]# tuned-adm active Current active profile: virtual-guest
Change/Switch the Tuning Profile
[root@server ~]# tuned-adm profile hpc-compute [root@server ~]# tuned-adm active Current active profile: hpc-compute
Recommend the suitable profile for the system
[root@server ~]# tuned-adm recommend virtual-guest
Switch to the recommended profile
[root@server ~]# tuned-adm profile virtual-guest [root@server ~]# tuned-adm active Current active profile: virtual-guest
