% Processor Time (Processor _Total)无法超过100%,但%Processor Time (Process _Total)能超过。
Examining Processor Time Data:
On multiprocessor systems, the Processor\% Processor Time value reported by System Monitor will never exceed 100 percent for any particular processor or thread. On the other hand, the value of the % Processor Time reported for the Process object can report values over 100 percent; if such values occur, this could indicate that threads of the process are cumulatively using more than 100 percent of a processor. To get more detailed information, use the Thread object counters to analyze the processor time each thread within a process is using. Investigating other data described in this section, such as DPC activity or context switching, might help you to interpret high processor-time values.
多处理器系统中,由系统监视报告的处理器Processor Time%值对任何个别处理器或线程不会超出100%。另一方面,进程对象Processor Time%报告值能超出100%,如果超出就意味着该进程的这些线程在累加地超出100%使用一个处理器。要得到更详尽的信息,使用线程对象计数器去分析该处理器在一个进程里使用每个线程的时间。调查在这部分描述的其它数据,如DPC活动或上下文切换,可能会帮助你去解释高Processor Time%值。
