再测Golang JSON类库

json

类库

主要是针对上述的类型进行，本人采用了对不同的类库使用不同的结构体（仅仅是结构体名称不同，字段顺序和类型一样）。

环境

环境为MacBook Pro（Core i5处理器/8GB内存）go1.8.3 darwin/amd64

代码

bench代码如下：

package jsonbenchimport ("encoding/gob""encoding/json""github.com/json-iterator/go""github.com/mailru/easyjson""github.com/pquerna/ffjson/ffjson""testing"
