几种web框架的相应速度比较(comparisionofruby,nodejs,java)

结论:  其实如果纯粹输出 Hellow world的话, 大家都差不多. 关键还是要看实际的应用情况( 读取数据库) 

. 

今天看到 express 框架的最好相应速度是 :  2200 req/s .一时兴起, 打算对比下 其他几种框架的速度. 

使用的命令是ab:

$ ab -n 1000 -c 1000 http://localhost:3000/

没有读取数据库,都是纯文字hello world. 

咱们看一下. 

1. sinatra:   

require 'sinatra'

get '/' do
  "Hello World!"
end

$ ruby test_sinatra.rb 

跟 express 一样, 每秒 2000个左右请求, 1800 ~ 2500浮动. 大部分都在1800 ~ 2000

2. express , 跟sinatra一样一样的. 

3. java : 算了.  太复杂. ... 从头到尾需要 WEB-INF,  xml, jar 等搭建各种东西.... 算了吧... 看了下 stackoverflow上一个人给出的测试,  700 req/s 

4. python tornado:  没有经过任何优化, ( 跟sinatra, expressjs 一样)

import tornado.ioloop
import tornado.web

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

application = tornado.web.Application([
    (r"/", MainHandler),
])

if __name__ == "__main__":
    application.listen(8888)
    tornado.ioloop.IOLoop.instance().start()

每秒处理1000个请求 .  但是我估计是没有使用 uwsgi  + nginx 造成的?  不清楚了.
