让我首先说说Orchard是一个出色的CMS，从目前为止我所看到的，我更喜欢它而不是Umbraco.

Let me start by saying that Orchard is a brilliant CMS, from what I've seen of it so far I prefer it to Umbraco.

但是有一个警告，由于应用程序池内存的限制，我在廉价的共享主机上运行一个非常小的Orchard站点时遇到了问题(实际上，我也在使用winhost). Orchard的内存非常消耗，在我的情况下，在几个页面视图中，它会跳到约100mb的内存.大多数共享托管软件包将应用程序池限制为100mb，因此在我的情况下它将在以下位置回收应用程序池每隔一个页面浏览量.例如，请参见此线程.我最终改为使用Umbraco.

But one word of warning, I had problems running a very small Orchard site on cheap shared hosting (in fact I was also using winhost) because of app pool memory limits. Orchard is quite memory hungry and in my case would jump to around 100mb of memory within a few page views. Most shared hosting packages limit the app pool to 100mb so in my case it was recycling the app pool on every other page view. See this thread as an example. I ended up using Umbraco instead.

对不起，我知道这是一个话题，不能回答多租户问题.但是在开发初期就对此进行测试.

Sorry, I know this is a bit off topic and doesn't answer the multi-tenancy question. But test for this early on in development.
