如何获得命中数,例如:
(pprof) top
Total: 2525 samples
298 11.8% 11.8% 345 13.7% runtime.mapaccess1_fast64
268 10.6% 22.4% 2124 84.1% main.FindLoops
不,持续时间如下:
(pprof) top
2220ms of 3080ms total (72.08%)
Dropped 72 nodes (cum <= 15.40ms)
Showing top 10 nodes out of 111 (cum >= 60ms)
flat flat% sum% cum cum%
1340ms 43.51% 43.51% 1410ms 45.78% runtime.cgocall_errno
env:我使用golang1.4,添加以下代码。
defer pprof.StopCPUProfile()
f, err := os.Create("innercpu.pprof")
if err != nil {
fmt.Println("Error: ", err)
}
pprof.StartCPUProfile(f)
