Overview
There are four CPU Power Management Polices that can be selected for an ESXi host:
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 power policy, 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. The following performance metrics were similar to the balanced CPU Power Management Policy.
Although there were no significant gains in performance when changing the CPU Power Management Policy to high performance, it is a good practice for production databases. By changing the power management policy to high performance, the administrator ensures that no power management features will impact future performance.
Implementation Steps
Use the following steps to update the power management policy:
