   He Dennis,
   Very nice overview! Do you know if the VDI settings are also valid for an ESXi host that is used for RDS workloads?
   Thanks!

      VDI or RDS are the same type of workload (serving desktops), so you could use those settings.

         Thanks Dennis!
         One more question:
         In the table above you recommend to set Power Management on “Performance” for the VDI use-case while in part 3 you write that it is best to put Power Management on “custom” in order to disable EIST:

         Enhanced Intel Speedstep (EIST)
         EIST is a technology whereby the frequency of processor cores can be lowered (through P-states) by software to reduce power consumption. It works in conjunction with P-states.
         When the ability of using EIST is disabled, Turbo Boost is also disabled!
         My recommendation is to let the Power Management setting control this setting.
         For VDI environments whereby the changes between P-state give a small delay in the desktop experience: my recommendation is to Disable EIST for VDI/TS.

         The Power Management option must be set to CUSTOM otherwise this setting is ignored!

         Can you please explain?

   HI AlphenIT, you’re correct! Power Management should be set to Custom otherwise those 2 settings (EIST/Turbo Boost) will be ignored.
