Different platforms will have different BIOS naming so the following is mainly for reference: -#. Before starting consider resetting all BIOS settings to their default. +#. Establish the steady state for the system, consider reviewing BIOS settings desired for best performance characteristic e.g. optimize for performance or energy efficiency. -#. Disable all power saving options such as: Power performance tuning, CPU P-State, CPU C3 Report and CPU C6 Report. +#. Match the BIOS settings to the needs of the application you are testing. -#. Select **Performance** as the CPU Power and Performance policy. +#. Typically, **Performance** as the CPU Power and Performance policy is a reasonable starting point. -#. Disable Turbo Boost to ensure the performance scaling increases with the number of cores. +#. Consider using Turbo Boost to increase the frequency on cores. -#. Set memory frequency to the highest available number, NOT auto. - -#. Disable all virtualization options when you test the physical function of the NIC, and turn on ``VT-d`` if you wants to use VFIO. +#.
