The aeson package
A JSON parsing and encoding library optimized for ease of use and high performance.
To get started, see the documentation for the Data.Aeson module below.
Parsing performance on a late 2013 MacBook Pro (2.6GHz Core i7), running 64-bit GHC 7.10.1, for mostly-English tweets from Twitter's JSON search API:
6.4 KB payloads, English: 7570 msg/sec (47.6 MB/sec)
14.6 KB payloads, Japanese: 3261 msg/sec (46.6 MB/sec)
Encoding performance on the same machine and data:
6.4 KB payloads, English: 22738 msg/sec (142.9 MB/sec)
14.6 KB payloads, Japanese: 15911 msg/sec (227.4 MB/sec)
(A note on naming: in Greek mythology, Aeson was the father of Jason.)
