測試環境:
伺服器配置: 4 x Intel(R) Xeon(R) CPU E5405 @ 2.00GHz, 4G記憶體, 作業系統: CentOS 5.3 x86_64
nginx前端 + 4 tornado(0.2) web process
tornado: http://www.tornadoweb.org (已被牆)
測試情境:
http get請求,伺服器端直接返回"hello world"
代碼及nginx配置:
main.py:
#!/usr/bin/python
# -*- coding: utf-8 -*-
"""web main"""

from tornado.web import RequestHandler, Application, authenticated
#from rockps.auth import AuthHandler

self.write("hello world")
settings = {
}
application = Application([
(r"/", MainHandler),
], **settings)
if __name__ == "__main__":
http_server = HTTPServer(application)
http_server.listen(8081)
IOLoop.instance().start()

測試結果:
點擊率可以超過7000,但後面再加使用者開始往下掉,請求開始出錯,最合適的時候大概3500個使用者
持續運行後,串連數穩在1萬。
