1    /FILE

    Initializes the file counters for the specified file or for all
    files.

2    /PERFORMANCE

    Initializes all performance counters.

3    /WAIT

    /WAIT=seconds (default = 90)
    /NOWAIT

    Specifies the maximum amount of time, in seconds, that you are
    willing to wait for command completion.  If the Registry server
    does not complete the request in the specified interval, REG$CP
    returns REG-F-NORESPONSE. The default interval is 90 seconds.
    /NOWAIT is equivalent to specifying /WAIT=0, but there may still
    be a short wait period.
