The following is throwing an OutOfMemoryException, for XML snippits that are very short and simple (e.g., <ABC def='123'/>): public static T DeserializeXmlNode<T>(XmlNode node) { try { return (T)new XmlSerializer(typeof(T)) .Deserialize(new XmlNodeReader(node)); } catch (Ex...

Why does IIS use so much more RAM than WebDev (ASP.NET development web server)?

I have an ASP.NET 2.0 page with many repeating blocks, including a third-party server-side control (so it's not just plain HTML). Each is quite expensive to generate, in terms of both CPU and RAM. I'm currently using a standard Repeater control for this. There are two problems with this simple approach: The entire page must be rendere...
