| Library | Time to read (s) | Time to write (s) | Memory footprint of json value (MB) | Remarks |
|---|---|---|---|---|
| jsoncons | 10.461 | 4.055 | 420 | Uses sorted std::vector of key/value pairs for objects, expect smaller memory footprint.Uses slightly modified grisu3_59_56 implementation by Florian Loitsch plus fallback for printing doubles, expect faster serializing. |
| nlohmann | 13.969 | 7.135 | 486 | Uses std::map for objects. Uses slightly modified Grisu2 implementation by Florian Loitsch for printing doubles, expect faster serializing. |
| rapidjson | 3.361 | 3.007 | 439 | Uses custom floating point parsing, expect faster parsing. Uses girsu3 for printing doubles, expect faster serializing. Uses custom allocation and flat map for objects, expect smaller memory footprint. |
| jsoncpp | 57.998 | 28.81 | 2245 | Uses std::map for both arrays and objects, expect larger memory footprint. |
| taojson | 17.253 | 6.868 | 860 | Uses modified google/double conversion routines for parsing doubles. Uses modified jeaiii/itoa routines for outputting integers. Uses slightly modified Grisu2 implementation by Florian Loitsch for printing doubles, expect faster serializing. |
