About aeson-native

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.)
