I found this benchmark for different IoC in .NET. Personally I’ve been using Unity, Ninject and SimpleInjector. I like SimpleInjector because it is very simple and surprisingly it is quite fast compared with the rest. Performance is just one of the aspect of IoC but it doesn’t always mean everything
