CommandBuffer.DrawMesh much slower than CommandBuffer.DrawRenderer?

    I am changing some of my code from using CommandBuffer.DrawRenderer to use CommandBuffer.DrawMesh so I don't need Renderer components. I expected their performance to be about the same, but it seems that DrawMesh is actually about 2x slower than DrawRenderer. I have timed it using cached input values so it is not a matter of argument evaluation overhead, and I am using the overloads that most closely match eachother.

    Is this expected? It doesn't seem right that DrawMesh should be so much slower.

    This is in Unity 5.6.0b9
