**Deprecated: On Go 1.11.2 goroutine pool has already slower than native `go` keyword.**

# Goroutine Pool

The pool implementation of Go goroutine, it is useful to avoid heavy pressure of `runtime.morestack ` when using goroutine.

It could recycle rather than free goroutines after executed. If the recycled goroutines not be stack reduced yet, then there is no need to request more stack.

## Benchmark

```

goos: darwin

goarch: amd64

pkg: eleme/nex/utils/gp

BenchmarkGoPool-4          	 2000000	       753 ns/op	      32 B/op	       1 allocs/op

BenchmarkGo-4              	 5000000	       318 ns/op	       0 B/op	       0 allocs/op

BenchmarkMorestackPool-4   	 1000000	      2551 ns/op	      64 B/op	       3 allocs/op

BenchmarkMoreStack-4       	  300000	      3758 ns/op	      16 B/op	       1 allocs/op

```

## Usage

```go

package main

import (

  "time"

  "github.com/ethe/GoroutinePool"

)

func main() {

  pool := gp.New(20 * time.Second)  // set idle timeout

  pool.Go(func() {}) // same as `go func(){}()`

}

```

## Lock-free Queue

It also contains a lock-free queue (linked list) minimal implementation.

```go

package main

import (  

  "fmt"

  "github.com/ethe/GoroutinePool"

)

func main() {

  queue := NewQueue()

  queue.Put(1)

  fmt.Println(queue.Get())

}

```
