pypy with twisted vs nodejs

浏览数：122 / 时间：2015年06月09日

看到网上都说nodejs处理并发请求速度很快.对比了一下pypy + twisted 单线程模型下

pypy+twisted完胜 nodejs 最少比nodejs快2倍以上

nodejs 结果:

pypy + twisted

nodejs代码:

var http = require("http");
http.createServer(function(request, response) {
response.writeHead(200, {"Content-Type": "text/plain"});
response.write("Hello World");
response.end();
}).listen(8888);

twisted代码:

import sys
from twisted.internet import epollreactor
epollreactor.install();
from twisted.internet import reactor

from twisted.web import http

class MyRequestHandler(http.Request):
    pages={
        ‘/‘:‘Hello world!‘,
        ‘/test‘:‘<h1>Test</h1>Test Page‘,
        }
    def process(self):
        if self.pages.has_key(self.path):

            self.setHeader("Content-Type", "text/plain")
            self.write(self.pages[self.path])

        else:
            self.setResponseCode(http.NOT_FOUND)
            self.write("<h1>Not Found</h1>Sorry, no such page.")
        self.finish()
class MyHttp(http.HTTPChannel):
    requestFactory=MyRequestHandler
class MyHttpFactory(http.HTTPFactory):
    protocol=MyHttp
if __name__=="__main__":
    reactor.listenTCP(8080,MyHttpFactory())
    reactor.run()
