Description Gurpreet Singh 2024-01-11 13:18:29 UTC

Description of problem:

Section 3.5 NFV BIOS Settings of the "Configuring NFV Guide" specifies the BIOS setting recommendation for NFV deployments.

The following parameters for BIOS are relevant and should be added to the list as well.

ProcTurbo: Disabled
SubNumaClustering: Disabled
NUMA Group Size Optimization: Clustered

SubNumaClustering: Disabled

Sub-NUMA Clustering: When enabled, Sub-NUMA Clustering divides the processor’s cores, cache, and memory into multiple NUMA domains. Enabling this feature can increase performance for workloads that are NUMA aware and optimized. Note: When this option is enabled, up to 1GB of system memory may become unavailable.

ProcTurbo: Disabled

Intel Turbo Boost Technology: Turbo Boost Technology enables the processor to transition to a higher frequency than the processor’s rated speed if the processor has available power and is within temperature specifications. Disabling this option reduces power usage, and also reduces the system’s maximum achievable performance under some workloads.

NUMA Group Size Optimization: Clustered.

NUMA Group Size Optimization: Use the NUMA Group Size Optimization option to configure how the system ROM reports the number of logical processors in a NUMA (Non-Uniform Memory Access) node. The resulting information helps the operating system group processors for application use. Clustered: Optimizes groups along NUMA boundaries, providing better performance
