I read a blog post recently where someone wrote a simple test app that used 3 different methods to set a property of a class 1000 times and tracked the overall performance. The results were a bit eye-popping:

• Reflection: 20 seconds
• Dynamics: .6 second
• Normal Property Setter: .01 second

Dynamics appear to offer a significant performance boost over reflection. Of course, it could/will vary with regard to how dynamic is used. I work with an application that uses a great deal of reflection and I’m interested to see how I might be able to switch it over to using dynamic more and see if I can boost performance.
