如果您的系统主要任务是提供Web应用，那么您可以停掉图形界面，而将其所用的内存和CPU资源用于您的服务。
The columns to observe are "us," "sy," and "id," which denotes CPU utilization time in user space, system space, and system idle time in percentage.
请注意“us”、“sy”和“id”列，它们分别表示用户空间和系统空间的CPU利用率百分比以及系统空闲时间。
Your system is merely running too many applications at the same time, or running a small number of very CPU-intensive operations.
您的系统可能仅仅只是同时运行了太多的应用程序，或者正在运行少量cpu密集型的操作。
If you loose 5% of a processor power every time you add a CPU to your system, then your "scalability factor" is 0.95.
如果每添加一个CPU到系统，都会失去5%的处理器功率，那么您的可扩展性系数为0.95。
