Oj

Optimized JSON (Oj), as the name implies was written to provide speed optimized JSON handling.

Oj has several dump or serialization modes which control how Objects are converted to JSON. These modes are set with the :mode option in either the default options or as one of the options to the dump() method.

:strict mode will only allow the 7 basic JSON types to be serialized. Any other Object will raise and Exception.
:null mode replaces any Object that is not one of the JSON types is replaced by a JSON null.
:object mode will dump any Object as a JSON Object with keys that match the Ruby Object's variable names without the '@' character. This is the highest performance mode.
:compat mode is is the compatible with other systems. It will serialize any Object but will check to see if the Object implements a to_hash() or to_json() method. If either exists that method is used for serializing the Object. The to_hash() is more flexible and produces more consistent output so it has a preference over the to_json() method. If neither the to_json() or to_hash() methods exist then the Oj internal Object variable encoding is used.
