Performance

Test Script

Test maximum single-threaded throughput for two minutes.

```go package main

import ( "fmt" "github.com/Netflix/spectator-go/v2/spectator" "time" )

func elapsed(start time.Time) float64 { return time.Now().Sub(start).Seconds() }

func main() { location := "udp" // location := "unix" config, _ := spectator.NewConfig(location, nil, nil) registry, _ := spectator.NewRegistry(config) defer registry.Close() // add tags with some length, to simulate more real-world conditions tags := map[string]string{"location": location, "version": "correct-horse-battery-staple"}

maxDuration := float64(2 * 60)
start := time.Now()

fmt.Printf("start spectator-go %s benchmark\n", location)
iteration := 1
for elapsed(start) < maxDuration {
    registry.Counter("spectator-go.publish", tags).Increment()
    if iteration % 500000 == 0 {
        fmt.Printf("iterations=%v elapsed=%v\n", iteration, elapsed(start))
    }
    iteration++
}

fmt.Printf("iterations=%v rate/sec=%v\n", iteration, float64(iteration) / elapsed(start))

} ```
