I think in my test code, what affect the performance maybe the cpu branches
misses? The row num is bigger than the column num, so in column-wise
traverse, the inner loop is easier to predict.
perf result:
row-wise
0.034014712741,811 branch-misses #
1.05% o
The test code is below:
package main
import (
"testing"
)
const rowSize = 100
const colSize = 100
var array [rowSize][colSize]int
func BenchmarkRow(b *testing.B) {
b.ResetTimer()
for i := 0; i < b.N; i++ {
sum := 0
for r := 0; r < rowSize; r++ {
for c := 0; c < colSize; c++ {
sum += array[r
I got it.Thank you for your help

I recently had a goroutine leak problem, the code i reduced is like this:
https://play.golang.org/p/YW4hWoZZ7CD.
The program is long-running and the finalizer is not called
The RoomObj is deleted from map， why was it not released？ Is it refereed by
the asyncChan object？
I don't understand he
