It disables power saving mechanisms and enables sysctl settings that improve throughput performance of disk and network IO. CPU governor is set to performance and CPU energy performance bias is set to performance. It also disables transparent hugepages, locks CPU to the low C states (by PM QoS) and tunes sysctl regarding semaphores. .SH "FILES" .nf .I /etc/tuned/* .I /usr/lib/tuned/* .SH "SEE ALSO" .BR tuned (8) .BR tuned\-adm (8) .BR tuned\-profiles (7) .BR tuned\-profiles\-atomic (7) .BR tuned\-profiles\-sap (7) .BR tuned\-profiles\-mssql (7) .BR tuned\-profiles\-oracle (7) .BR tuned\-profiles\-realtime (7) .BR tuned\-profiles\-nfv\-host (7) .BR tuned\-profiles\-nfv\-guest (7) .BR tuned\-profiles\-cpu\-partitioning (7) .BR tuned\-profiles\-compat (7) .BR tuned\-profiles\-postgresql (7) .BR tuned\-profiles\-openshift (7) .BR tuned\-profiles\-spectrumscale\-ece (7) .SH AUTHOR .nf Jaroslav Škarvada
