| 摘 要： | Linux内核2．6．24采用了新的调度器CFS（Completely Fair Scheduler），以公平的原则对待所有任务。其性能和对交互进程的响应速度都超过之前版本内核的O（1）调度器，并且算法与实现也更简单。先简单对比了O（1）和CFS，然后结合源代码对CFS的算法和实现作了分析。

| Abstract: | Linux kernel 2.6.24 has adopted a new Completely Fair Scheduler,the principle of it is the fair treatment on all tasks.Its performance and responding speed on interactive tasks are all superior to previous scheduler O(1),and its algorithm and implementation are simpler too.In this paper we draw a simple comparison between CFS and O(1),and then briefly analyse the algorithm and implementation of CFS according to its source code. |
