5)perf bench benchmark 是衡量性能的标准方法,对于同一个目标,如果能够有一个大家都承认的 benchmark,将非常有助于”提高内核性能”这项工作。 6)perf lock 锁是内核同步的方法,一旦加了锁,其他准备加锁的内核执行路径就必须等待,降低了并行。因此对于锁进行专门分析应该是调优的一项重要工作。 7)perf Kmem Per...

- 交换(swap):内存紧缺时, MM 可能会把一些暂时不用的内存页转移到访问速度较慢的次级存储设备中(如磁盘, SSD), 以腾出空间,这个操作叫交换, 相应的存储设备叫交换设备或交换空间. - 文件缓存页(PageCache Page):内核会利用空闲的内存, 事先读入一些文件页, 以期不久的将来会用到, 从而避免在要使用时再去...
