uvloop is a fast, drop-in replacement of the built-in asyncio
|
|
event loop. uvloop is implemented in Cython and uses libuv
|
|
under the hood.
|
|
|
|
The project documentation can be found
|
|
`here <http://uvloop.readthedocs.org/>`_. Please also check out the

`wiki <https://github.com/MagicStack/uvloop/wiki>`_.

Performance
|
|
-----------
|
|
|
|
uvloop makes asyncio 2-4x faster.

|
The above chart shows the performance of an echo server with different
|
|
message sizes. The *sockets* benchmark uses ``loop.sock_recv()`` and
|
|
``loop.sock_sendall()`` methods; the *streams* benchmark uses asyncio
|
|
high-level streams, created by the ``asyncio.start_server()`` function;
|
|
and the *protocol* benchmark uses ``loop.create_server()`` with a simple
|
|
echo protocol. Read more about uvloop in a
|
|
`blog post <http://magic.io/blog/uvloop-blazing-fast-python-networking/>`_
|
|
about it.

Installation
|
|
------------
|
|
|
|
uvloop requires Python 3.5 or greater and is available on PyPI.
|
|
Use pip to install it::
|
|
|
|
$ pip install uvloop
|
|
|
|
|
|
Using uvloop
|
|
------------
|
|
|
|
To make asyncio use uvloop, you can install the uvloop event
|
|
loop policy:
|
|
|
|
.. code:: python
|
|
|
|
import asyncio
|
|
import uvloop
|
|
|
|
asyncio.set_event_loop_policy(uvloop.EventLoopPolicy())
|
|
|
|
or, starting with uvloop 0.12:
|
|
|
|
.. code:: python
|
|
|
|
import uvloop
|
|
|
|
uvloop.install()
|
|
|
|
|
|
Building From Source
|
|
--------------------
|
|
|
|
To build uvloop, you'll need Python 3.5 or greater:
|
|
|
|
1. Clone the repository:
|
|
|
|
.. code::
|
|
|
|
$ git clone --recursive git@github.com:MagicStack/uvloop.git
|
|
$ cd uvloop
|
|
|
|
2. Create a virtual environment and activate it, for example:
|
|
|
|
.. code::
|
|
|
|
$ python3.7 -m venv uvloop-dev
|
|
$ source uvloop-dev/bin/activate
|
|
|
|
3. Install development dependencies:
|
|
|
|
.. code::
|
|
|
|
$ pip install -r requirements.dev.txt
|
|
|
|
4. Build and run tests:
|
|
|
|
.. code::
|
|
|
|
$ make && make test
