纯python实现的web: tornado性能测试

测试环境: 服务器配置: 4 x Intel(R) Xeon(R) CPU E5405@ 2.00GHz， 4G内存, 操作系统: CentOS 5.3 x86_64
nginx前端 + 4 tornado(0.2) web process
tornado: http://www.tornadoweb.org (已被墙)
测试场景:
http get请求，服务器端直接返回"hello world"
代码及nginx配置:main.py:

http://common.cnblogs.com/images/copycode.gif
#!/usr/bin/python
# -*- coding: utf-8 -*-
"""web main"""

from tornado.httpserver import HTTPServer
from tornado.ioloop import IOLoop
from tornado.web import RequestHandler, Application, authenticated

#from rockps.auth import AuthHandler


class MainHandler(RequestHandler):
    def get(self):
      self.write("hello world")
      
settings = {
}

application = Application([
    (r"/", MainHandler),
], **settings)


if __name__ == "__main__":
    http_server = HTTPServer(application)
    http_server.listen(8081)
    IOLoop.instance().start()

    # Only retry if there was a communication error, not a timeout
    # on the Tornado server (to avoid propagating "queries of death"
    # to all frontends)
    proxy_next_upstream error;

    server {

      # Allow file uploads
      client_max_body_size 50M;

      location ^~ /static/ {
            root /var/www;
            if ($query_string) {
                expires max;
            }
      }
      location = /favicon.ico {
            rewrite (.*) /static/favicon.ico;
      }
      location = /robots.txt {
            rewrite (.*) /static/robots.txt;
      }

      location / {
            proxy_pass_header Server;
            proxy_set_header Host $http_host;
            proxy_set_header X-Real-IP $remote_addr;
            proxy_set_header X-Scheme $scheme;
            proxy_pass http://frontends;
      }
    }

测试结果:http://pic002.cnblogs.com/img/fengmk2/200910/2009102816430196.png

点击率可以超过7000，但后面再加用户开始往下掉，请求开始出错，最合适的时候大概3500个用户

持续运行后，连接数稳在1万。

结论，2个字:
