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.
