高性能python服务器karlooper性能简介

By | 2016/07/05

hello大家好,
今天给大家介绍一个python的高性能web framework,目前是beta版本,
我们将其与tornado进行性能对比:
OS:Linux 4.2
Python:2.7.11
项目github地址:点击
先给大家看两段代码:
1、tornado的代码:
[code lang=”python”]
# -*-coding:utf-8-*-

import tornado.ioloop
import tornado.web

class MainHandler(tornado.web.RequestHandler):
def get(self):
self.write("Hello, World!")

Handlers=[
(r"/hello", MainHandler),
]

application = tornado.web.Application(Handlers)

if __name__ == "__main__":
application.listen(9999)
tornado.ioloop.IOLoop.instance().start()

[/code]
2、karlooper代码
[code lang=”python”]
# -*-coding:utf-8-*-

from karlooper.web.application import Application
from karlooper.web.request import Request

class MainHandler(Request):
def get(self):
return self.http_response("Hello,World!")

handlers = {
"/hello": MainHandler
}

if __name__ == ‘__main__’:
application = Application(handlers, port=9999)
application.run()

[/code]
我们使用Apache Bench进行性能测试:
测试结果如下:

通过以上数据对比,我们发现,同等条件下:
karlooper的性能要明显高于tornado。
