Formed in 2009, the Archive Team (not to be confused with the archive.org Archive-It Team) is a rogue archivist collective dedicated to saving copies of rapidly dying or deleted websites for the sake of history and digital heritage. The group is 100% composed of volunteers and interested parties, and has expanded into a large amount of related projects for saving online and digital history.
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. Please also check out the 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
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
Call uvloop.install() before calling asyncio.run() or
manually creating an asyncio event loop:
import asyncio
import uvloop
async def main():
# Main entry-point.
...
uvloop.install()
asyncio.run(main())Building From Source
To build uvloop, you'll need Python 3.5 or greater:
Clone the repository:
$ git clone --recursive git@github.com:MagicStack/uvloop.git $ cd uvloop
Create a virtual environment and activate it:
$ python3.7 -m venv uvloop-dev $ source uvloop-dev/bin/activate
Install development dependencies:
$ pip install -r requirements.dev.txt
Build and run tests:
$ make $ make test
