12synopsis: Fast JSON parsing and encoding
14homepage: https://github.com/bos/aeson
15bug-reports: https://github.com/bos/aeson/issues
18 A JSON parsing and encoding library optimized for ease of use
21 To get started, see the documentation for the @Data.Aeson@ module
24 Parsing performance on a late 2013 MacBook Pro (2.6GHz Core i7),
25 running 64-bit GHC 7.10.1, for mostly-English tweets from Twitter's
28 * 6.4 KB payloads, English: 7570 msg\/sec (47.6 MB\/sec)
30 * 14.6 KB payloads, Japanese: 3261 msg\/sec (46.6 MB\/sec)
32 Encoding performance on the same machine and data:
34 * 6.4 KB payloads, English: 22738 msg\/sec (142.9 MB\/sec)
36 * 14.6 KB payloads, Japanese: 15911 msg\/sec (227.4 MB\/sec)
