[New-bugs-announce] [issue7451] improve json decoding performance

[Antoine Pitrou]

New submission from Antoine Pitrou <pitrou at free.fr>:

This patch does two things:
- it speeds up decoding of JSON objects by doing fewer temporary allocations
- it reduces memory use of decoded JSON objects by reusing key strings
when they appear several times in a JSON string
