This is a great paper; it is very readable and motivated and I learned quite a bit. I'm also now looking forward to perusing the 2012 Ninja C paper.
One small change I would make to the preprint would be to better normalize the graph symbols. In particular, failing to read the legends of each graph carefully might cause readers to misattribute results in subsequent graphs (for example, my mind wanted to associate Intel's HRC with "the lighter gray ones with the boxes", which is not a stable representation across all graphs).
