ASP.NET MVCScaffolding is very slow

Question

We try to use ASP.NET MVC Scaffolding ( http://blog.stevensanderson.com/2011/01/13/scaffold-your-aspnet-mvc-3-project-with-the-mvcscaffolding-package , http://mvcscaffolding.codeplex.com/). Great tool, but please any advice why is it so slow? The scaffolding of simple model in an empty project (as described in this tutorial) takes about 15 seconds, which is slow still acceptable, but after we added some scaffolding logic based on our custom metadata attributes, the scaffolding of a model with some one-to-many relationships takes 5 minutes and more, which makes it unusable. Anyways to improve the performance?

I know it is an old question but maybe this helps someone else. It creates exclusions for Windows Defender for all folders and processes of Visual Studio
