|
.SH NAME
|
|
tuned\-profiles\-sap\-hana - description of profiles provided for the SAP HANA
|
|
|
|
.SH DESCRIPTION
|
|
These profiles provides performance optimizations for the SAP HANA applications.
|
|
|
|
.SH PROFILES
|
|
The following profiles are provided:
|
|
|
|
.TP
|
|
.BI "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.
|
|
|
|
.TP
|
|
.BI "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.
