django自带wsgi server vs 部署uwsgi+nginx后的性能对比

一.下面先交代一下测试云主机

cpu：

root@alexknight:/tmp/webbench-1.5# cat /proc/cpuinfo |grep model
model        :
model name    : Intel(R) Core(TM) i5-4260U CPU @ .40GHz
root@alexknight:/tmp/webbench-1.5#

mem：

root@alexknight:/tmp/webbench-1.5# free -m
             total       used       free     shared    buffers     cached
Mem:
-/+ buffers/cache:
Swap:                          

二.测试对比

测试工具为webbench.

• 下面是django自带wsgi webserver的性能

root@alexknight:/tmp/webbench-1.5# webbench -c  -t  http://115.28.21.25:8008/
Webbench - Simple Web Benchmark 1.5
Copyright (c) Radim Kolar -, GPL Open Source Software.

Benchmarking: GET http://115.28.21.25:8008/
 clients, running  sec.

Speed= pages/min,  bytes/sec.
Requests:  susceed,  failed.

大概能承受20路并发，当上升到25路时，会开始出现失败请求。

• 下面用uwsgi+nginx取代自带的wsgi server

root@alexknight:/tmp/webbench-1.5# webbench -c  -t  http://115.28.21.25:8000/
Webbench - Simple Web Benchmark 1.5
Copyright (c) Radim Kolar -, GPL Open Source Software.

Benchmarking: GET http://115.28.21.25:8000/
 clients, running  sec.

Speed= pages/min,  bytes/sec.
Requests:  susceed,  failed.

大概能承受170路并发，效果还算明显的，当请求继续上升时，就会开始出现失败请求。
