Restrict Cores/Ram used by ArcGIS Server

Question

Sometimes you want to run ArcGIS Server (4 Core License) on a machine with more than four cores (maybe you only have a single machine deployment or other Software installed on the server). The additional cores are not needed/intended for ArcGIS Server.

Is there a way, similar to the one available for Geoanalytics Server, to limit CPU Cores and RAM to be consumed by ArcGIS Server? I did not find anything documented. Do the mentioned parameters work by any change on ArcGIS Server as well?

* percentageMaxAllowedComputeCores—This represents the maximum CPU cores (as a percentage of total available on a machine) that will be used by the compute platform worker process on a single node. If the specified value translates to less than one CPU core, one CPU core will be used for the compute platform worker process.
* percentageMaxAllowedComputeMemory—This represents the maximum memory (as a percentage of total available memory on a machine) that will be used by the compute platform worker process on single node.

"In the past, people have used “Windows System Resource Manager” to do this. But, the Windows Server 2012 documentation says “Windows System Resource Manager (WSRM) is deprecated."Limiting CPU Cores on Windows Server 2012 - Esri Community

There is the https://www.esri.com/content/dam/esrisites/en-us/media/technical-papers/licensing-arcgis-enterprise-deployments-in-virtualized-and-cloud-environments.pdf paper regarding virtual cores, but many machines have a 1:1 core equivalency.

Thanks!  This still leaves the question on how to make the affinity setting stick even after reboot and the question on how to restrict the memory. I could not find an affinity equivalent for the memory...

Regarding your first question about ArcSOC.exe, you won't need to do anything for that process if you address the ArcGISServer.exe process because CPU affinity is inherited by child or spawned processes.

Hi, thank you. However, affinity settings revert to default after a restart. I found it possible to create a shortcut like this:

cmd.exe /c start "software" /High /affinity hexadecimalvalueforcores  "path"

But the ArcGIS Server Processes autostart.
Is there a way to add execution parameters for ArcGIS\Server\framework\runtime\ArcGIS\bin\ArcSOC.exe and ArcGIS\Server\framework\etc\service\bin\ArcGISServer.exe to permanently assign the affinity even after reboot?
