Dsched-nice-design.rst16 Linux的nice级别总是非常脆弱,人们持续不断地缠着我们,让nice +19的任务占用
24 (人们对这一变化很满意),而且我们还故意校正了线性时间片准则,使得nice +19
40 -20 | +19
44 因此,如果有人真的想renice任务,相较线性规则,+19会给出更大的效果(改变
51 nice +19级别运行数量颇多的应用程序)。
53 因此,对于HZ=1000,我们将nice +19改为5毫秒,因为这感觉像是正确的最小
54 粒度——这相当于5%的CPU利用率。但nice +19的根本的HZ敏感属性依然保持不变,
55 我们没有收到过关于nice +19在CPU利用率方面太 _弱_ 的任何抱怨,我们只收到
87 更一致的nice +19支持:在新的调度器中,nice +19的任务得到一个HZ无关的
