本次测试在windows平台下进行。

在性能测试前先了解一款测力测试软件: siege

一款开源的压力测试工具，可以根据配置对一个WEB站点进行多用户的并发访问，记录每个用户所有请求过程的相应时间，并在一定数量的并发访问下重复进行。

windows版软件下载：https://download.csdn.net/download/masonwu21/6254773

使用方法：

siege -c 200 -r 10 -b example.url

-c 是并发量，-r 是重复次数, url文件就是一个文本，每行都是一个url，它会从里面随机访问的。

测试代码

#Django
django-admin startproject django_test
python manage.py startapp app_test
python manage.py migrate
python manage.py runserver

#Tornado
# coding=utf-8

import tornado.ioloop
import tornado.web

class MainHandler(tornado.web.RequestHandler):
    def get(self):
        self.write("Hello, world")
def make_app():
    return tornado.web.Application([
        (r"/", MainHandler),
    ])
if __name__ == "__main__":
    app = make_app()
    app.listen(8888)
    tornado.ioloop.IOLoop.current().start()

#Flask
# coding=utf-8
from flask import Flask
import logging
app = Flask(__name__)

@app.route('/')
def hello_world():
    return 'Hello World!'

if __name__ == '__main__':
    app.run(port=8888, debug=False)
