How do I measure and improve the efficiency of Parallel jobs in CI/CD?

Measuring and improving the efficiency of parallel jobs in CI/CD pipelines is crucial for faster deployment and reduced time to feedback. This can be achieved through various strategies such as analyzing job duration, optimizing resources, and utilizing performance monitoring tools.

        // Example: Measuring job execution time in a CI/CD pipeline
        $start_time = microtime(true);

        // Simulate a parallel job
        exec("php artisan queue:work --daemon &");

        // End time and calculate total execution time
        $end_time = microtime(true);
        $execution_time = $end_time - $start_time;

        echo "Total Execution Time: " . $execution_time . " seconds";
