Overview
There are four CPU Power Management Polices that can be selected for a virtual machine:
Many databases support critical business functions where performance is an enterprise priority. In this best practice the CPU Power Management Policy was changed from its default of Balanced to High Performance to ensure the best possible performance.
Recommendation
The results from changing the CPU Power Management Policy from Balanced to High Performance did not show any significant increases in performance. All of the performance metrics shown below were similar to those of a CPU Power Management Policy set to Balanced.
Although we observed no significant gains in performance, changing the CPU Power Management Policy to High Performance is a good practice for production databases. By doing so, the administrator ensures that power management features will not impact future performance.
Implementation Steps
To set the ESXi Power Policy to High Performance:
