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) .
