In order to achieve the best possible real-time performance, some options can be set in the BIOS menu. The options below are taken from a BIOS on a Dell machine. Computers from other manufacturers may contain similar options.

Which options are ideal depends on the system. It is normally recommended to disable 'C-State Control'. However, a test system (Dell Tower OPTIPLEX 9010; 2 x i7-3770 @3.4Gz) showed better performance with this option enabled.
