NAME
       tuned-profiles-sap-hana - description of profiles provided for the SAP
       HANA


DESCRIPTION
       These profiles provides performance optimizations for the SAP HANA
       applications.


PROFILES
       The following profiles are provided:


       sap-hana
              A performance optimized profile for the SAP HANA applications.
              It allows sleep states down to C3 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.


       sap-hana-kvm-guest
              A performance optimized profile for the SAP HANA application
              when running as virtual guest on KVM. It loads the cpuidle-
              haltpoll driver to ensure lower latencies (at the cost of a
              higher power consumption).  The clocksource is set to TSC,
              skew_tick is enabled.
