Reproduction Steps

1. run following code

package main

import (
	"global/gctuner"
)

func main() {

	const gb = 1024 * 1024 * 1024
	threshold := gb * 4

	gctuner.Tuning(uint64(threshold))
	println(gctuner.GetGCPercent())

	// 执行具体的业务逻辑
	for {
		data1 := make([]int, 10000, 10000)
		data2 := make([]int, 10000, 10000)
		for i, _ := range data1 {
			data1[i] = i
		}
		for i, _ := range data2 {
			data2[i] = i
		}
		result := 0
		for i, _ := range data1 {
			result += data1[i] * data2[i]
		}
	}

}

2. Then run it with command, You will see the gc info

 GODEBUG=gctrace=1 go run main.go
