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.

28
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.
