### DESCRIPTION The Set-RASCPUOptimizationSettings cmdlet modifies Parallels RAS CPU optimization settings using the specified parameters and their values.\ \ All parameters are optional.\
### PARAMETERS \ -**CPUExcludeList \**\ Specifies items in the CPUExclude list.\
``` Required? false ``` ``` Position? named ``` ``` Default value ``` ``` Accept pipeline input? false ``` ``` Accept wildcard characters? false ``` \ -**SiteId \**\ The site ID to which the RAS CPU Optimization settings refer.\
``` Required? false ``` ``` Position? named ``` ``` Default value 0 ``` ``` Accept pipeline input? false ``` ``` Accept wildcard characters? false ``` \ -**StartUsage \**\ The CPU usage percentage above which the CPU Optimization will start working.\
``` Required? false ``` ``` Position? named ``` ``` Default value ``` ``` Accept pipeline input? false ``` ``` Accept wildcard characters? false ``` \ -**CriticalUsage \**\ The CPU usage percentage above which a process will be set to idle priority.\
``` Required? false ``` ``` Position? named ``` ``` Default value ``` ``` Accept pipeline input? false ``` ``` Accept wildcard characters? false ``` \ -**IdleUsage \**\ The CPU usage percentage below which a process will be set to realtime priority.\
``` Required? false ``` ``` Position? named ``` ``` Default value ``` ``` Accept pipeline input? false ``` ``` Accept wildcard characters? false ``` \ -**EnableCPUOptimization \**\ Enables or disables the "CPU Optimization" option.\
``` Required? false ``` ``` Position? named ``` ``` Default value ``` ``` Accept pipeline input? false ``` ``` Accept wildcard characters? false ``` \ -**Replicate \**\ Enables or disables the "Replicate settings" option (replicate settings to all sites).\
``` Required? false ``` ``` Position? named ``` ``` Default value ``` ``` Accept pipeline input? false ``` ``` Accept wildcard characters? false ``` \ \ ``` This cmdlet supports the common parameters: Verbose, Debug, ``` ``` ErrorAction, ErrorVariable, WarningAction, WarningVariable, ``` ``` OutBuffer, PipelineVariable, and OutVariable.

GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com. ## Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://docs.parallels.com/landing/ras-powershell-api-guide/v19/parallels-ras-powershell-admin-module/commands/set-rascpuoptimizationsettings.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
