TuneD can be used to optimize the system's performance and power consumption for different use cases, and consists of the following main components:

TuneD Profiles

A profile is a set of predefined optimizations for system components, such as CPUs, and disk devices. Some profiles, such as latency-performance and network-latency, are configured to prioritize performance, whilst others, such as powersave, are configured to use less power. Select the profile to use on a server according to the workload and the required power-performance balance of those tasks. Custom TuneD profiles with extra optimizations for a specific system can also be used.

tune-adm command line utility

Use the tune-adm command to manage profiles on the server, list available profiles, and select the current system profile.

For more information, see the tuned-adm(8) and tuned(8) manual pages.
