IWbemHiPerfProvider interface
The IWbemHiPerfProvider interface enables providers to supply refreshable objects and enumerators. High-performance providers can be loaded in-process to either WMI or a client process. When the provider is loaded in-process to a client process, it uses the CLSID specified as the ClientLoadableCLSID value in the __Win32Provider representing the provider instance definition.
