以下是 PHP 與 Node.js 的相同演算法進行效能比較。
Example Source Code:Node.js。
var i, a, b, c, max; max = 1000000000; var d = Date.now(); for (i = 0; i < max; i++) { a = 1234 + 5678 + i; b = 1234 * 5678 + i; c = 1234 / 2 + i; } console.log(Date.now() - d);
Example Source Code:PHP。
$a = null; $b = null; $c = null; $i = null; $max = 1000000000; $start = microtime(true); for ($i = 0; $i < $max; $i++) { $a = 1234 + 5678 + $i; $b = 1234 * 5678 + $i; $c = 1234 / 2 + $i; } var_dump(microtime(true) - $start);
