Benchmark Performance Timing with System.Diagnostics.Stopwatch

The Tip: Relying on Time.time for code benchmarking lacks high-precision timing accuracy.

How to Use: Use System.Diagnostics.Stopwatch to measure execution timing down to ticks or fraction of a millisecond.

using System.Diagnostics;
using UnityEngine;

public class PerformanceBenchmark : MonoBehaviour
{
    private void Start()
    {
        Stopwatch timer = Stopwatch.StartNew();
        
        // Execute block to measure
        ExecuteTask();
        
        timer.Stop();
        UnityEngine.Debug.Log($"Completed in: {timer.ElapsedMilliseconds} ms ({timer.ElapsedTicks} ticks)");
    }

    private void ExecuteTask() { }
}
