-*** Optional: In the event of cluster performance issues, from the *Latency Sensitivity* list, select *High*.
+*** Optional: In the event of cluster performance issues, from the *Latency Sensitivity* list, select *High*. Ensure that your VM's CPU and memory reservation have the following values:
+**** Memory reservation value must be equal to its configured memory size.
+**** CPU reservation value must be at least the number of low latency virtual CPUs multiplied by the measured physical CPU speed.
 *** Click *Edit Configuration*, and on the *Configuration Parameters* window, click *Add Configuration Params*. Define the following parameter names and values:
 **** `guestinfo.ignition.config.data`: Locate the base-64 encoded files that you created previously in this procedure, and paste the contents of the base64-encoded Ignition config file for this machine type.
 **** `guestinfo.ignition.config.data.encoding`: Specify `base64`.
