Virtual dispatch makes it much harder for an optimizing compiler to inline method calls, so there is a significant performance hit even for callsites that do end up always calling the same method.

In AOT compiled languages at least, it is an often performed optimization in JIT compilers. Also, I was explicitly asking besides performance.

  Since you have the concrete type, you can do stuff like storing it inline (which may not be possible if you don't know its size).
