gmmpool

A multi level memory pool for Golang:

The design thoughts are detailed in golang multi-level memory pool design and implemention(in Chinese🇨🇳).

Installation

go get github.com/liudanking/gmmpool

Usage

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
