Use this benchmark ut:
```go
func BenchmarkReceiveDataFromClosedChan(b *testing.B) {
count := b.N
ch := make(chan struct{}, count)
for i := 0; i < count; i++ {
ch <- struct{}{}
}
b.ResetTimer()
for range ch {
}
}
```
Benchmark 10 times(`go test -bench=.`), and then use `benchstat` got the result:
```shell
name old time/op new time/op delta
ReceiveDataFromClosedChan-5 12.0ns ± 1% 11.4ns ± 0% -5.54% (p=0.000 n=10+8)
```
