Does Django run in single thread by default？

Question

By reading the code, I found it seems that Django run in single thread by default.

However, when I use sleep(15) in my view function and open two web to request my function. They return the response almost at the same time!

so, I do not know why does it happened……

my Django version is 1.9

Django itself does not determine whether it runs in one or more threads. This is the job of the server running Django.

The development server used to be single-threaded, but in recent versions it has been made multithreaded. Other servers such as Apache/mod_wsgi, gunicorn, or uwsgi, have their own defaults and can be configured in a number of ways; often they use multiple processes rather than threads.
