I find this kind of profiling fascinating, intuition is often a very bad adviser when it comes to raw performance. By carefully profiling you can definitely learn a lot of things about the platform and surprises hide in every corner. I had the same kind of experiences when I did some profiling on iPhone about index buffer performance with sparse vertex buffers (I was trying to do culling by rendering subsets of the index buffer, I don't remember exactly).
