I wonder whether the author used the 'optimize_for=SPEED' parameter in Protocol Buffers. Seems relevant, and since the author didn't mention it, I suppose he probably didn't.
I personally have a hard time accepting that PB is actually orders of magnitude slower than JSON, especially given the fact that PB prides itself in its efficiency.
i didn't use the optimize_for=SPEED option but will do that right now and update it in half an hour.
EDIT: I just added the option *optimize_for=SPEED to the .proto file, and it increases the speed of the Protocol Buffers by around 5% (still 10 x more than JSON with Python).

it's not always slower, but in certain situations yes. it seems that the Python implementation is especially slow -- would be nice to see the results with C++. anyone cares to give it a shot?
