Hello everyone,

Golang is said that has a great performance. So I decide to create a small benchmark to compare performance of PHP, NodeJS, and Golang.

My Environment

• MacOS 3.1 GHz Intel Core i5
• PHP 7.2.6
• NodeJS 10.7.0
• Go 1.11.2

Implementation code

PHP Code

function calc($total) {
	$before = microtime(true);
	$sum = 0;
	for ($i = 0; $i < $total; $i++) { 
		$sum += $i;
	}

	$after = microtime(true);

	echo (round($after - $before, 3) * 1000);
	echo "\n";
}

NodeJS Code

function calc(total) {
	var before = Date.now(),
		sum = 0;

	for (var i = 0; i < total; i++) {
		sum += i;
	}

	var after = Date.now();

	console.log(after - before);
}

Golang Code

func calc(total int) {
	before := time.Now().UnixNano()
	sum := 0
	for i := 0; i < total; i++ {
		sum += i
	}
	after := time.Now().UnixNano()
	fmt.Println((after - before) / 1000000)
}
