在linux早期设计中,当调用fork命令来创建子进程时,子进程会将父进程的所有资源做一次全部拷贝复制工作。这个拷贝复制的工作是相当耗时的,影响系统的整体性能。 当引入了COW机制之后,当fork用来创建子进程时,子进程只拷贝页表的内存,不再拷贝物理地址对应的真正数据了。
In contrast, the Linux kernel is tightly controlled by Linus Torvalds and some core Linux code keepers. As long as these people are around, there is little chance that the Linux kernel will fork like the Unix kernel did. The only differences among Linux distributions in terms of kernel is ...
