I forked his benchmark[1], updated all the libraries to their current versions, and modified it so it would work with reflectutils.

Here's what I came up with. The numbers are time (in milliseconds) spent chewing through roughly 170Mb of JSON. In case the rich text tables don't convey, I also have an image: http://cl.ly/Pm1A

Jackson is impressive, but not dominating. The results make me very curious about Protostuff, which I had never heard of before: https://code.google.com/p/protostuff/
