## Improve JSON performance I would like to talk my progress of daily contribution to Ruby world. Last year, I talked about my performance improvement to Ruby core at RubyKaigi 2017. I'm planing to talk the improvement to json gem as following with 5 minutes at RubyKaigi 2018 LT. - https://github.com/flori/json/pull/345 - https://github.com/flori/json/pull/346 When my pull request will be merged, json gem performance will improve as JSON.parse() -> 60.9 % faster JSON.generate() -> 3.5 times faster みんな大好きな JSON が速くなると、世界がよりよくなる・・・はず。 Thanks.
