flask 四種wsgi方式對比（tornado，Gunicorn，Twisted，Gevent）

使用工具：siege

代碼結構：

hello.py

templates

|--hello.html

hello.py代碼：

from flask import Flask, render_template
app = Flask(__name__)

@app.route('/')
@app.route('/<name>')
def index(name=None):
    return render_template('hello.html',name=name)

if __name__ == '__main__':
    app.run(host='0.0.0.0',port=13579, debug=False)
           

hello.html代碼：

from Flask</title>
{% if name %}
<h1>Hello {{ name }}!</h1>
{% else %}
<h1>Hello World!</h1>
{% endif %}
