Hi,

The patch looks interesting, having around 8% improvement on that sounds
attractive. Nathan, do you plan to come back to it and finish the
review?

One side note, I think it would be great to properly cite the white
paper the patch is referring to. Besides paying some respect to the
authors, it will also make it easier to actually find it. After a quick
search I found only some references to [1], but this link doesn't seem
to be available anymore.
