With SAP NetWeaver installed on Windows Server 2008 R2 you may experience high CPU usage in wmiprvse.exe. This CPU usage increases with the number of SAP worker processes.
The high CPU usage is caused by an efficiency issue in the way WMI collects the performance counters.
Please contact SAP for more information and reference SAP note 1919492 - "100% CPU consumption of WmiPrvSE.exe process".
The callstack of the affected thread will end in perfproc!GetProcessVaData and that is where the high CPU will accumulate. This can be collected and viewed by using WPRUI and WPA. These are part of the Windows Performance Toolkit.
