17 A JSON parsing and generation library optimized for ease of use
18 and high performance.

20 Parsing performance with GHC 6.12.3 on a late 2010 MacBook Pro
21 (2.66GHz Core i7), for mostly-English tweets from Twitter's JSON
22 search API:
23 .
24 * English, 854 bytes: 29029 msg\/sec (23.6 MB/sec)
25 .
26 * English, 6.4 KB: 6407 msg\/sec (40.3 MB/sec)
27 .
28 * English, 31.2 KB: 1265 msg\/sec (38.8 MB/sec)
29 .
30 * English, 61.5 KB: 585 msg\/sec (35.2 MB/sec)
31 .
32 Handling heavily-escaped text is a little more work. Here is
33 parsing performance with Japanese tweets, where much of the text
34 is entirely Unicode-escaped:

40 Encoding performance on the same machine and data:

50 * Japanese, 44.1 KB: 1505 msg\/sec (64.8 MB/sec)
51 .
52 With GHC 7.0.2, the story is mixed: parsing is 20-40% slower than
53 GHC 6.12.3, while encoding performance ranges from about the same
54 to twice as fast (on numeric data).
