PROFILES

16       The following profiles are provided:
17
18
19       sap-hana
20              A  performance  optimized profile for the SAP HANA applications.
21              It allows sleep states down to C3 and  enables  sysctl  settings
22              that  improve throughput performance of disk and network IO. CPU
23              governor is set to performance and CPU energy  performance  bias
24              is  set  to performance. It also disables transparent hugepages,
25              locks CPU to the low C states (by PM QoS) and tunes  sysctl  re‐
26              garding semaphores.

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