I\'ve found some 2008 benchmark results for testing the performance of several of the top .NET DI/IoC containers here. But I haven\'t been able to find any updated results.
In my case, speed of IoC container has been an important factor. I've had an application that performs many injections and found that Ninject was slowing the application down considerably. Taking out the IoC completely solved the performance issues. I will be looking into other solutions.
