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/>`_.

Performance
|
|
-----------
|
|
|
|
uvloop makes asyncio 2-4x times 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 performance

Installation
|
|
------------
|
|
|
|
uvloop requires Python 3.5 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, alternatively, you can create an instance of the loop
|
|
manually, using:
|
|
|
|
.. code:: python
|
|
|
|
loop = uvloop.new_event_loop()
|
|
asyncio.set_event_loop(loop)
|
|
|
|
|
|
Development of uvloop
|
|
---------------------
|
|
|
|
To build uvloop, you'll need Cython and Python 3.5. The best way
|
|
is to create a virtual env, so that you'll have ``cython`` and
|
|
``python`` commands pointing to the correct tools.
|
|
|
|
1. ``git clone --recursive git@github.com:MagicStack/uvloop.git``
|
|
|
|
2. ``cd uvloop``
|
|
|
|
3. ``make``
|
|
|
|
4. ``make test``
