The tabs will wait for a bit and then some of them will show `Internal Server Error`.

### What happens

The first tab will make your app create a connection to the database and wait for some seconds before replying back and closing the database connection.

Then, for the request in the next tab, your app will wait for one second less, and so on.

* 您计算机上运行的每个应用程序背后都有一些进程，每个正在运行的程序，每个窗口等。并且通常在计算机打开时**同时**运行许多进程。
* **同一程序**可以有**多个进程**同时运行。

如果您检查操作系统中的“任务管理器”或“系统监视器”（或类似工具），您将能够看到许多正在运行的进程。

例如，您可能会看到有多个进程运行同一个浏览器程序（Firefox、Chrome、Edge 等）。 他们通常每个tab运行一个进程，再加上一些其他额外的进程。

现在我们知道了术语“进程”和“程序”之间的区别，让我们继续讨论部署。

## 启动时运行

And, for example, you will probably see that there are multiple processes running the same browser program (Firefox, Chrome, Edge, etc). They normally run one process per tab, plus some other extra processes.
