We officially suggest that SharePoint be on a different server than PIM to avoid these performance issues. If you must have them on the same server, you can try excluding the process from cainstrm.
To do so, follow these steps:
1- Stop all CA ControlMinder services.
2- Open a command line window and run the following command:
net stop cainstrm
3- Open the regedit utility from the Run command line window.
4- Navigate to the following path:
5- Modify the ExcludeProcess registry entry value to include the SharePoint exe file.
6- From the command line window, run the following command:
net start cainstrm
7- Start the CA ControlMinder services.
