Google Chrome浏览器在打开新标签时的确切功能是什么？ [英] What does the Google Chrome exactly do when a new tab is opened?

问题描述

今天，我观察到一个有趣的行为。我使用的是Windows XP-sp3操作系统。

当我在Google Chrome浏览器中打开一个新选项卡时，查看任务管理器，创建一个新进程。

但是，一段时间后，此进程终止。

为什么它显示出这种行为？是否由于系统调用 vfork（）？子进程是否立即调用 exec（）？

只有在Google Chrome浏览器或所有其他浏览器运行在类似的方式？

解决方案

AFAIK Chrome为每个标签维护一个进程，也是一些插件的进程。他们更喜欢多进程架构而不是多线程架构，因为当您正在使网络应用程序始终与网络进行通信时，您可能期望接收可能导致内存不足的数据包。因此，多进程将阻止除一个进程以外的所有进程，而不是多线程将终止这些选项卡。

Today, i observed an interesting behavior. I am using windows XP-sp3 OS.
When i open a new tab in Google Chrome & view the task manager, a new process is created.
But, after some time, this process is terminated.

Why it is showing such kind of behavior? Is it due to system call vfork()? Does the child process immediately call exec()?

Does it happen only with Google Chrome or all other browsers behave in a similar fashion?

解决方案

AFAIK Chrome maintains one process for each tab, also one process for some plugins too. They preferred multi-process architecture over multi-threaded one because when you are making network application which communicate with network all the time, you can expect to receive packets which can garble the memory. So having multi-process will prevent all but one process, as opposed to multi-threaded will kill the the tabs.
