I did some brief googling after reading your comment and I did find one article showing clientside protobuf being faster than JSON[0]. However they didn't isolate parsing - the only thing they measure is total request time to a Java spring application, so the JSON slowdown will include the Java JSON serialisation overhead as well as the request size/network overhead. My instinct is that these two will heavily favour protobuf making the JSON parse still likely to be faster.
It also shows a difference of 388ms (protobuf) vs 396ms (JSON) which is pretty negligible. Certainly not orders of magnitude.

Do you have other sources?
