Erlang JSON libraries: serialization performance?

Question

There are a number of JSON libraries available for Erlang, and it\'s not clear to me which have the best performance characteristics (and, secondarily, ease of use), especially

Answer 1

I use rfc4627.erl (I stumbled upon it, and performance has not been an issue)

However, I do expect the different native erlang libraries to perform similarly well. They share ideas (as witnessed in the code comments). AFAIK mochijson and rfc4627 share the same source erlang format.

eep018 is C, and as it is striving to implement ... hrm ... eep-0018, the term_to_json native encoder that might be included in a future version of Erlang. Never tried it and doesn't seem actively maintained.

My final recommendation is go with mochiweb's mochijson(2). It is the de facto standard and actively maintained, used by, among others, CouchDB and Facebook.

As for choosing between mochijson and mochijson2, this might help you.
