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:

#!/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()

nginx.conf:

user root;

worker_processes 1;

error_log /var/nginx_error.log;

pid /var/run/nginx.pid;

events {

worker_connections 51200;

use epoll;

}

http {

# Enumerate all the Tornado servers here

upstream frontends {

server 127.0.0.1:8081;

server 127.0.0.1:8082;

server 127.0.0.1:8083;

server 127.0.0.1:8084;

}

#include /etc/nginx/mime.types;

default_type application/octet-stream;

access_log /var/log/nginx/access22.log;

keepalive_timeout 65;

proxy_read_timeout 200;

sendfile on;

tcp_nopush on;

tcp_nodelay on;

gzip on;

gzip_min_length 1000;

gzip_proxied any;

gzip_types text/plain text/html text/css text/xml

application/x-javascript application/xml

application/atom+xml text/javascript;

# 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 {

listen 8085;

# 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:

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:

牛X
