# Benchmark

![benchmark](http://jsoniter.com/benchmarks/go-benchmark.png)

Source code: https://github.com/json-iterator/go-benchmark/blob/master/src/github.com/json-iterator/go-benchmark/benchmark_medium_payload_test.go

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

```go

import "encoding/json"

json.Marshal(&data)

```

with

```go

import jsoniter "github.com/json-iterator/go"

var json = jsoniter.ConfigCompatibleWithStandardLibrary

json.Marshal(&data)

```

Replace

```go

import "encoding/json"

json.Unmarshal(input, &data)

```

with

```go

import jsoniter "github.com/json-iterator/go"

var json = jsoniter.ConfigCompatibleWithStandardLibrary

json.Unmarshal(input, &data)

```
