Unlike debugging, DTrace can be switched on or off at will, and you do not need to provide a special build of your application to take advantage of the tracing functionality.

与调试不同，D Trace可以根据需要打开或关闭，而且使用跟踪功能不需要以特殊方式构建应用程序。

Because the overhead to run trace is significant, it is important to ensure that all tracing is turned off when you are not debugging problems.

因为运行跟踪的开销是不可忽略的，所以，当您不在调试问题的时候，确保关闭所有的跟踪很重要。
