H A Dsched-nice-design.rst20 nice级别的支持在历史上是与时间片长度耦合的，而时间片单位是由HZ滴答驱动的，
21 所以最小的时间片是1/HZ。
47 这种方法在一定程度上奏效了一段时间，但后来HZ=1000时，它导致1 jiffy为
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，
58 总结一下：我们一直想让nice各级别一致性更强，但在HZ和jiffies的限制下，以及
85 为了解决第一个抱怨（nice级别不够“有力”），调度器与“时间片”、HZ的概念
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
