-#### Conclusions
-
-Both parsers provided by this library are, for sufficiently large JSON documents, about 42% faster than the reference implementation.
-
-The relation between the size of the JSON input and the parsing duration is linear.
-
-Preloading the content of a JSON file into a `String` instead of using a [`FileReader`][FileReader] yield no significant performance improvement.
