令人惊叹的bjoern
标签：wsgi, bjoern最近由于业务量的增加，我们的rpc服务器偶尔会出现请求处理过慢的情况．所以我用想到了那个老外对主流wsgi服务器进行测试中表现最好的bjoern．之前是没有用过，今天把它安装到生产环境，处理速度确定提高不少．
项目地址
https://github.com/jonashaag/bjoern
安装
安装前确保系统上已安装了 libev
centos7 安装 libev
yum install libev-devel
ubuntu安装安装 libev
sudo apt-get install libev-dev
然后就可以用pip安装bjoern了
pip install Bjoern
用法
# Bind to TCP host/port pair:
bjoern.run(wsgi_application, host, port)
# TCP host/port pair, enabling SO_REUSEPORT if available.
bjoern.run(wsgi_application, host, port, reuse_port=True)
# Bind to Unix socket:
bjoern.run(wsgi_application, 'unix:/path/to/socket')
# Bind to abstract Unix socket: (Linux only)
bjoern.run(wsgi_application, 'unix:@socket_name')
Alternatively, the mainloop can be run separately:
bjoern.listen(wsgi_application, host, port)
bjoern.run()
You can also simply pass a Python socket(-like) object. Note that you are responsible for initializing and cleaning up the socket in that case.
bjoern.server_run(socket_object, wsgi_application)
bjoern.server_run(filedescriptor_as_integer, wsgi_application)
