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。
