Update recommended BIOS settings for performance to be more appropriate
for a wider variety of applications, and allow users to select the most
appropriate settings for their use case, e.g. some users may wish to
have Turbo Boost enabled.

The following are some recommendations on BIOS settings. 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.
+#. Disable all virtualization options when you test the physical function of the NIC, and turn on VT-d if you wants to use VFIO.

Applied, thanks
Note: Such doc should be out of Linux guide if they apply also
to BSD and Windows.
