Influence of power management on VDI performance
Tuning your image can have a huge impact on the performance of your environment. Tools like VMware OSOT or the Citrix Optimizer can help you with this. While most of the individual settings within your image have a small impact on the performance there is one setting outside of your image which has a big impact. The power management of your hypervisor. This setting is a bit hidden and easy to forget. Setting it correctly in your BIOS isn’t always enough.
Where you can set the power management in the BIOS is different for every vendor. The naming for the option is also different per vendor. Most vendors allow you to set four different flavors of power management, going from low, balanced, to high and as additional flavor: OS controlled power management. Important to know is that OS controlled power management means the BIOS allows to be overruled by the OS. It can mean you have to set the power management in the hypervisor itself.
For example in the vCenter you can set the power management under the Configure tab of the hosts itself. To make it more difficult for you; VMware created in the vCenter two tabs in the config of your hosts that are called power management. The power management tab underneath hardware should allow you to set an active policy. Make sure it is set to high performance!
