# gmmpool

A multi level memory pool for Golang:

![](https://ws1.sinaimg.cn/large/44cd29dagy1fociejthjoj20n40ckgm0.jpg)

The design thoughts are detailed in [golang multi-level memory pool design and implemention](https://liudanking.com/arch/golang-multi-level-memory-pool-design-implementation/)(in Chinese🇨🇳).

## Installation

`go get github.com/liudanking/gmmpool`

## Usage

```go

package main

import (

	"bytes"

	"log"

	"github.com/liudanking/gmmpool"

)

func main() {

	pool := gmmpool.NewMultiLevelPool([]gmmpool.PoolOpt{

		gmmpool.PoolOpt{Num: 10, Size: 1024},     // level 0

		gmmpool.PoolOpt{Num: 10, Size: 1024 * 2}, // level 1

	})

	buf := pool.Get(1025)

	defer pool.Put(buf)

	data, err := buf.ReadAll(bytes.NewReader(make([]byte, 8)))

	if err != nil {

		log.Fatal(err)

	}

	log.Print(data)

}

```

## Benchmark (compared with ioutil.ReadAll, x19 speed up)

```

BenchmarkStdReadAll-4             200000          5969 ns/op

BenchmarkMultiLevelPool-4        5000000           311 ns/op

```
