#1145-7 で話していたjson-pureについて、機会があったので調べたところ、次のような速度差があった。

ある短いJSONを1万回パースしたところ
json: 0.000078
json_pure: 0.000401
という壊滅的な結果が出た。さて、俺はこの結果を見てしまったわけだが…

• 遅い
• なんかパッケージとかで面倒なこともあるらしい
• json_pureは2.1が出ているのにmikutterでは~>1.8の指定のまま放置されている

という問題があるため、json_pureの利用をやめる方向で検討する。

検証に使ったコード

require 'benchmark'
require 'json/pure'
#require 'json'
