aeson: Fast JSON parsing and generation
A JSON parsing and generation library optimized for ease of use and high performance.
Parsing performance with GHC 6.12.3 on a late 2010 MacBook Pro (2.66GHz Core i7), for mostly-English tweets from Twitter's JSON search API:
854 bytes: 21054 msg/sec (17.1 MB/sec)
6.4 KB: 4545 msg/sec (28.6 MB/sec)
31.2 KB: 856 msg/sec (26.1 MB/sec)
61.5 KB: 403 msg/sec (24.2 MB/sec)
Handling heavily-escaped text is a little more work. Here is parsing performance with Japanese tweets, where much of the text is entirely Unicode-escaped:
14.6 KB: 1250 msg/sec (17.9 MB/sec)
44.1 KB: 363 msg/sec (15.6 MB/sec)
Encoding performance on the same machine and data:
854 bytes: 10647 msg/sec (8.7 MB/sec)
6.4 KB: 2098 msg/sec (13.2 MB/sec)
31.2 KB: 422 msg/sec (12.9 MB/sec)
61.5 KB: 219 msg/sec (13.2 MB/sec)
(A note on naming: in Greek mythology, Aeson was the father of Jason.)
