使用apache和django的virtualbox linux guest太慢了

我有一个在virtualbox中运行的CentOS客户端 . 它运行apache和django . 我所有的django网站源文件都在Windows主机目录中 . 我在CentOS中安装了这个目录 . 文件系统是vboxsf .

问题是，当我在Windows主机浏览器中访问来宾Apache URL时，它的加载非常慢 . 我的意思是浏览器等待时间大约是页面加载前的17秒 .

为了解决这个问题，我使用了python分析，但我无法使用此分析器数据找到问题 . 请在下面找到探查器数据 .

我认为共享文件系统导致问题，所以我只是将整个代码库本地复制到CentOS客户端，但是，我再次遇到相同的性能问题 .

任何帮助，将不胜感激 . 谢谢 .
