Raw Result (easyjson requires static code generation)

| | ns/op | allocation bytes | allocation times | | --------------- | ----------- | ---------------- | ---------------- | | std decode | 35510 ns/op | 1960 B/op | 99 allocs/op | | easyjson decode | 8499 ns/op | 160 B/op | 4 allocs/op | | jsoniter decode | 5623 ns/op | 160 B/op | 3 allocs/op | | std encode | 2213 ns/op | 712 B/op | 5 allocs/op | | easyjson encode | 883 ns/op | 576 B/op | 3 allocs/op | | jsoniter encode | 837 ns/op | 384 B/op | 4 allocs/op |

Always benchmark with your own workload. The result depends heavily on the data input.

Usage

100% compatibility with standard lib

Replace

import "encoding/json" json.Marshal(&data)

with

import jsoniter "github.com/json-iterator/go" var json = jsoniter.ConfigCompatibleWithStandardLibrary json.Marshal(&data)

Replace

with

import jsoniter "github.com/json-iterator/go" var json = jsoniter.ConfigCompatibleWithStandardLibrary json.Unmarshal(input, &data)
