@Jake, I start in Go. I'm not familiar with the use of pprof.
I do this
go tool pprof -list=calculate goRoutineBench /tmp/profile152563623/cpu.pprof
I get this
Total: 1.84mins
ROUTINE ======================== main.calculate in goRoutineBench.go
1.84mins 1.84mins (flat, cum) 99.86% of Total
. . 48:}
. . 49:
. . 50:func calculate(idRoutine int, steps int) {
. . 51: var (
. . 52: //possibles []string
130ms 130ms 53: possibles = []string{}
. . 54: numBatchs = 0
. . 55: t1 = time.Now()
. . 56: sum = 0
. . 57: )
. . 58:
. . 59: for {
. . 60: select {
. 10ms 61: case <-goroutineQuit:
. . 62: return
. . 63: default:
. . 64: //possibles = nil
. . 65: possibles = possibles[:0]
. . 66:
10.71s 10.71s 67: for _, nonce := range tryArr {
24.09s 24.16s 68: possibles = append(possibles,
nonce)
. . 69:
1.26mins 1.26mins 70: for _, r := range nonce {
. . 71: sum += int(r) * int(r) / 3
. . 72: }
. . 73: }
. . 74:
40ms 40ms 75: numBatchs++
. . 76: if numBatchs == 99 {
. . 77: t2 := time.Now()
. . 78:
. . 79: timeExecution := t2.Sub(t1) /
time.Millisecond
is this the right approach / method?
