我的网站是用MVC3，Entity Framework构建的，并且AutoFac被用作IoC容器。现在一个很大的问题是网站的w3wp.exe进程占用了太多内存。网站启动时，它会在一小段时间内使用300M，令牌内存高达1GB。我不知道如何解决它。mvc3 +实体框架+ autofac，网站占用太多内存
autofac配置

恐怕您必须将问题追踪到可以在此处显示的代码片段或代码区域。某些类型的autofac注册不会消耗我想象中的那么多内存。 – Jan 2011-12-20 13:57:33

你的'IUnitOfWork'是否实现'IDisposable'？您的DbContext/ObjectContext可能不会在请求后处理。 – Eranga 2011-12-20 14:21:00
