This is an improvement: we've reduced the number of context switches from four to two and reduced the number of data copies from four to three (only one of which involves the CPU).
改进的地方：我们将上下文切换的次数从四次减少到了两次，将数据复制的次数从四次减少到了三次(其中只有一次涉及到了CPU)。
Moreover, on this fairly slow 366 MHz chip, one million context switches can be performed in about 10 seconds (the number of threads involved is not particularly significant to the timing).
而且，在这个比较慢的 366MHz芯片上可以在大约10秒内执行一百万次上下文切换（所涉及的线程数对耗时并无重大影响）。
When you click the button, context switches to the sales lead application, and the component invokes the UI for creating a new sales lead and populates it with the available information.
当单击这个按钮时，将切换到潜在客户应用程序，同时组件调用UI创建新的潜在客户并使用可用信息进行填充。
Generally speaking, a system has an excellent chance of becoming CPU-bound if the CPU is 100 percent busy, has a large run queue compared to the number of CPUs, and more context switches than usual.
通常来说，如果某个系统的CPU是100%忙碌，并且相对于CPU的数目来说拥有大规模的运行队列，以及具有更为频繁的上下文切换，那么该系统很有可能成为CPU受限系统。
