> The real cost with JSON is when you have a 200MB manifest or build artifact and you need exactly two fields out of it.
There are SAX-like JSON libraries out there, and several of them work with a preallocated buffer or similar streaming interface, so you could stream the file and pick out the two fields as they come along.
