Available profiles:
- balanced                    - General non-specialized tuned profile
- desktop                     - Optmize for the desktop use-case
- 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.
- powersave                   - Optimize for low power consumption
- throughput-performance      - Broadly applicable tuning that provides excellent performance across a variety of common server workloads.  This is the default profile for RHEL7.
- virtual-guest               - Optimize for running inside a virtual guest.
- virtual-host                - Optimize for running KVM guests
