我的是双核的CPU，我的那个程序占用了 91%，可是那个空闲CPU还好多啊，能利用上吗，谢谢回复
%us 用户空间占用CPU百分比、
%sy 内核空间占用CPU百分比、
%ni 用户进程空间内改变过优先级的进程占用CPU百分比、
%id 空闲CPU百分比、
%wa 等待输入输出（I/O）的CPU时间百分比 、
%hi指的是cpu处理硬件中断的时间、%si指的是cpu处理软中断的时间 、
%st用于有虚拟cpu的情况，用来指示被虚拟机偷掉的cpu时间。 当然可以用上，取决于应用程序“会不会用”。 回复 1# wzw200

不要只关心你的CPU利用率了，91%我决定还是可以接受的。从你的输出来看，存在的问题是，只有2个core，但你的loadavg却接近9了，说明你系统中遇到了CPU瓶颈或者IO瓶颈。
好的，谢谢回复，还在查问题
