Go语言学习技巧之如何合理使用Pool

type Pool 
func (p *Pool) Get() interface{} 
func (p *Pool) Put(x interface{}) 
New func() interface{} 

package main
import (
 "fmt"
 "sync"
 "time"
)
type structR6 struct {
 B1 [100000]int
}
var r6Pool = sync.Pool{
 New: func() interface{} {
 return new(structR6)
 },
}
func usePool() {
 startTime := time.Now()
 for i := 0; i < 10000; i++ {
 sr6 := r6Pool.Get().(*structR6)
 sr6.B1[0] = 0
 r6Pool.Put(sr6)
 }
 fmt.Println("pool Used:", time.Since(startTime))
}
func standard() {
 startTime := time.Now()
 for i := 0; i < 10000; i++ {
 var sr6 structR6
 sr6.B1[0] = 0
 }
 fmt.Println("standard Used:", time.Since(startTime))
}
func main() {
 standard()
 usePool()
}
