Minimum Processor Idle Power Package State - No Package State. Minimum Processor Idle Power Core State - No C-states. Intel QPI Link Power Management - Disabled. HP Power Regulator - HP Static High Performance Mode. Apparently, this is the most important parameter that affects the performance. These recommendations are taken from SAP notes. Setting the highest values for these settings helped us to significantly increase the speed of VmWare ESXi hosts and to achieve a shorter response for SAP systems.
I will show you where these parameters are located. You may not know this, but these are installed by default settings, significantly reduce the speed of the memory and CPU. And, naturally, these parameters also affect performance. There are number of parameters in the settings of server's BIOS, which affect the power consumption of hardware. These days a lot of attention is paid to the ecology and green technologies, including manufacturers of servers.
