Recorder.elapsedNanoseconds

Description

Accumulated time of Begin/End pairs for the previous frame in nanoseconds. (Read Only)

Long-lasting operations (for example, on a preloading thread) might not end within a single frame. In this case, elapsedNanoseconds is calculated until the end of the frame, so you can always see activity for these operations.

using UnityEngine;
using UnityEngine.Profiling;

public class ExampleClass : MonoBehaviour
{
    Recorder behaviourUpdateRecorder;
    void Start()
    {
        behaviourUpdateRecorder = Recorder.Get("BehaviourUpdate");
        behaviourUpdateRecorder.enabled = true;
    }

    void Update()
    {
        if (behaviourUpdateRecorder.isValid)
            Debug.Log("BehaviourUpdate time: " + behaviourUpdateRecorder.elapsedNanoseconds);
    }
}

Use elapsedNanoseconds to retrieve timings of a code tagged with ProfilerMarker.Auto.

using UnityEngine;
using UnityEngine.Profiling;

public class Example
{
    public static void TimeSynchronousMethodWithMarkers()
    {
        var recorder = Recorder.Get("MyMarker");
        recorder.enabled = true; // Start measurements

        // Call method which uses MyMarker
        // MyMethod();

        recorder.enabled = false; // Stops measurements and makes data available immediately
        Debug.Log("MyMarker total time, ns: " + recorder.elapsedNanoseconds);
    }
}

In synchronous measurements that don't involve a frame change, elapsedNanoseconds only becomes a non-zero value after the Recorder is disabled.
