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

       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.
