1    /FILE

    Stop gathering counters for the specified file or for all files.

2    /PERFORMANCE

    Stop gathering 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.
