一篇关于django，tornado性能测试的非专业性报告

篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了一篇关于django，tornado性能测试的非专业性报告相关的知识，希望对你有一定的参考价值。

为什么要写这篇文章？

确实是因为博主最近实在太无聊了。闲的蛋疼只能装作很忙的样子。。。故有了这篇。

测试说明

！！这里先说明一下，由于本文出自博主实验环境（windows 笔记本+VirtualBox虚拟linux）条件下，由于条件简陋，且测试代码均比较简单，故测试报告不能保证严谨准确，仅供参考和娱乐。

环境介绍

由于条件简陋，测试环境为本人自用thinkpad x240笔记本电脑（intel core i3 1.9GHZ + 8G内存）+VirtualBOX虚拟机（虚拟环境为centos6.9 64bit 处理器数量1 内存1024M） ，python版本2.7.13 ，django版本1.8.3，tornado版本4.5.2。测试中使用了gunicorn 版本19.7.1。nginx。（多么详细。。。），压力测试工具使用apache自带的 ab工具进行
简单说一下本次测试所写的代码（下面会详细贴出代码），在如此简陋的情况下，测试代码均为hello work状态。（即只利用框架输出index hello word）。

为了保证测试尽量严谨，每个项目压力测试均测试3次以上取平均值（如差异不大随机贴出一次结果。），更换项目后重启虚拟机测试。

不啰嗦了正式开始

一、django、tornado最基本代码测试对比

最基本测试，直接使用项目本身启动程序，即python xxx.py形式 不使用任何转发。

django

 
   
   
 
    
  
    
    
  
  1. #由于代码简单 这里只贴出views.py代码，其余代码均为初始化项目后默认未动。（urls.py除添加访问url外无其他修改）
    2.

    12. 
 
   
   
 
 
   
   
 
    
  
    
    
  
  1. #启动项目，开始测试
    2. 
  
    
    
  
  2. [root@centos1 untitled1]# python manage.py runserver 127.0.0.1:8888

可以看到默认情况下，吞吐率为347.47 [#/sec]

结果，默认情况下 django和tornado吞吐率方面几乎是没区别的。

二、django、tornado最基本代码模拟访问数据库测试对比

最基本测试，直接使用项目本身启动程序，即python xxx.py形式 不使用任何转发。模拟数据库访问 这里使用加一段ping代码来进行。（机器不行就不要真的搞个mysql访问了。抱歉抱歉。）

    9. 
  
    
    
  
    10. 
  
    
    
  
  10. def index(request):
    11. 
  
    
    
  
  11.     os.system("ping -c 1 www.baidu.com") #增加个这个代码，咱们ping 1次百度来模拟这里进行了数据库select访问。
    12. 
  
    
    
  
  12.     return HttpResponse("Hello world ! ")
    13. 
 
   
   
 
 
   
   
 
    
  
    
    
  
  1. [root@centos1 untitled1]# python manage.py runserver 127.0.0.1:8888
    2. 
  
    
    
  
  2. Performing system checks...
    3. 
  
    
    
  
    4.

可以看到这种情况下，吞吐率为4.28 [#/sec] 惨不忍睹！

结果，很显然这个对比是没有意义的，由于tornado的单线程的设计逻辑，导致在不使用非阻塞是方法编程时性能简直惨不忍睹。（ps：由于这里是模拟了数据库访问操作，在实际的环境中访问mysql的速度理论上远大于ping 1次的速度）

限于篇幅关系，我们下一篇将继续进行django和tornado的性能测试。
