No frills, simple gathering of execution stats. This is essentially no more than a convenient wrapper for time.Since.
Has a high footprint on performance but is more sensitive and granular than Go's profiler.
Useful when you have blocks of code that don't span across functions or that execute in just a few nanoseconds.
Since Chronos has a high footprint (the "quantum" conundrum), it is best to avoid nesting Chronos's.
For strong thread safety (at a cost on performance), use ChronosTS.
func main() {
ch := chronos.Builder{}.Build()
ch.Start()
doSomething()
ch.Stop()
ch.Println("doSomething")
}
// doSomething >> c: 1 e: 1.1425ms avg: 1.1425msfunc TestExample1(t *testing.T) {
coh1 := &chronos.Cohort{}
var wg sync.WaitGroup
for i := 1; i <= 10_000; i++ {
c1 := chronos.Builder{}.WithSamplingRate(100).BuildTS()
coh1.Add(c1)
wg.Add(1)
go func(c1 *chronos.ChronosTS) {
defer wg.Done()
for i := 1; i <= 1_000; i++ {
c1.Start()
time.Sleep(1 * time.Nanosecond)
c1.Stop()
}
}(c1)
}
wg.Wait()
coh1.Println("doSomething")
}
