Como fazer um medidor de desempenho simples:

import { performance } from 'node:perf_hooks';
import { memoryUsage } from 'node:process';

function measurePerformance(label: string, callback: () => unknown): void {
  if (global.gc) global.gc();

  const initialMemory = memoryUsage().heapUsed;
  const startTime = performance.now();

  callback();

  const endTime = performance.now();
  if (global.gc) global.gc();

  const finalMemory = memoryUsage().heapUsed;

  const executionTime = (endTime - startTime).toFixed(3);
  const memoryChangeKB = ((finalMemory - initialMemory) / 1024).toFixed(2);

  console.log(
    `${label.padEnd(12)} | Tempo: ${executionTime} ms | Δ Memória: ${memoryChangeKB} KB`,
  );
}
