H A Dsched-nice-design.rst11 调度器nice值设计
16 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
51 nice +19级别运行数量颇多的应用程序）。
63 nice级别的行为取决于 _绝对的_ nice级别，而nice应用程序接口本身从根本上
66 int nice(int inc);
71 注意，“inc”是相对当前nice级别而言的，类似bash的“nice”命令等工具是这个
74 在旧的调度器中，举例来说，如果你以nice +1启动一个任务，并以nice +2启动
78 第三个关于Linux nice级别支持的抱怨是，负数nice级别“不够有力”，以很多人
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
90 为了解决第二个抱怨（nice各级别不一致），新调度器令调用nice(1)对各任务的

92 CFS调度器处理nice级别和SCHED_BATCH的能力比之前的原始调度器更强：两种类型的工作负载
