那是什么意思?
http://linux.about.com/od/commands/l/blcmdl1_top.htm没有说什么?
us 的意思是使用。 sy 好像是系统。你?什么是ni? id是什么?什么是哇? si是什么?为什么这么多的CPU时间花在ni和sy上?
答案1
从man top
:
us, user : time running un-niced user processes
sy, system : time running kernel processes
ni, nice : time running niced user processes
wa, IO-wait : time waiting for I/O completion
hi : time spent servicing hardware interrupts
si : time spent servicing software interrupts
st : time stolen from this vm by the hypervisor
它没有说明什么id
意思,但我认为它代表“空闲”,因为对于我的系统来说它始终约为 85%,并且将所有数字相加得到 100%。
