As with "The Other msgpack module" -- performance seems to be lower than JSON.

is my JSON file.

The message pack version seems like it is half as big but takes twice as long to parse.

This is because it's hard to compete with the built-in json code in V8.
Though it also depends on the kind of data you're parsing. Strings are the
weak point here. Arrays of integers are super fast and compact.

There seems to be a significant difference in performance between 0.1.1 and 0.3.0 (sorry I didn't narrow it down more than that). I ran the benchmark.js from node-msgpack against node-msgpack, msgpack-js0.1.1 and msgpack-js0.3.0. Here are the results:

node-msgpack     pack:   2561 ms
