[ bsd3, deprecated, json, library, text, web ] [ Propose Tags ] [ Report a vulnerability ]
Deprecated in favor of aeson

A JSON parsing and encoding library optimized for ease of use and high performance.

Note: if you use GHCi or Template Haskell, please see the README file for important details about building this package, and other packages that depend on it: https://github.com/mailrank/aeson#readme

Parsing performance on a late 2010 MacBook Pro (2.66GHz Core i7), for mostly-English tweets from Twitter's JSON search API:

  • 0.8 KB, 32-bit GHC 6.12.3: 30538 msg/sec (24.9 MB/sec)

  • 0.8 KB, 64-bit GHC 7.0.3: 31204 msg/sec (25.4 MB/sec)

  • 6.4 KB, 32-bit GHC 6.12.3: 6731 msg/sec (42.3 MB/sec)

  • 6.4 KB, 64-bit GHC 7.0.3: 6627 msg/sec (41.7 MB/sec)

  • 11.8 KB, 32-bit GHC 6.12.3: 3751 msg/sec (43.2 MB/sec)

  • 11.8 KB, 64-bit GHC 7.0.3: 3381 msg/sec (38.9 MB/sec)

  • 31.2 KB, 32-bit GHC 6.12.3: 1306 msg/sec (39.8 MB/sec)

  • 31.2 KB, 64-bit GHC 7.0.3: 1132 msg/sec (34.5 MB/sec)

  • 61.5 KB, 32-bit GHC 6.12.3: 616 msg/sec (37.0 MB/sec)

  • 61.5 KB, 64-bit GHC 7.0.3: 534 msg/sec (32.1 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, 32-bit GHC 6.12.3: 2315 msg/sec (33.1 MB/sec)

  • 14.6 KB, 64-bit GHC 7.0.3: 1986 msg/sec (28.4 MB/sec)

  • 44.1 KB, 32-bit GHC 6.12.3: 712 msg/sec (30.7 MB/sec)

  • 44.1 KB, 64-bit GHC 7.0.3: 634 msg/sec (27.3 MB/sec)

  • 82.9 KB, 32-bit GHC 6.12.3: 377 msg/sec (30.5 MB/sec)

  • 82.9 KB, 64-bit GHC 7.0.3: 332 msg/sec (26.9 MB/sec)

Encoding performance on the same machine and data:

  • English, 854 bytes: 43439 msg/sec (35.4 MB/sec)

  • English, 6.4 KB: 7127 msg/sec (44.8 MB/sec)

  • Engish, 61.5 KB: 765 msg/sec (46.0 MB/sec)

  • Japanese, 14.6 KB: 4727 msg/sec (67.5 MB/sec)

  • Japanese, 44.1 KB: 1505 msg/sec (64.8 MB/sec)

(A note on naming: in Greek mythology, Aeson was the father of Jason.)
