By default, Intersoft 2007 product platform has the SmartWebResources set to Automatic mode. This automatic mode ensures compatibility with existing web application when developers migrated to 2007 platform, while at the same time attempting to utilize SmartWebResources in new web application whenever possible.
When you created a new web application and started to use WebGrid.NET version 5.0, the SmartWebResources is not configured initially. With the automatic mode as default behavior, WebGrid.NET will use physical resources since the SmartWebResources is not configured initially.
