Doctrine2とmysqliでのインサートの比較用

gistfile1.php

<?php
// 本番環境ではやらないでね！

$mysqli = mysqli_init();
$mysqli->real_connect("localhost","user_name","password","db_name");
if($error = mysqli_connect_error()){
	throw new RuntimeException($error);
}
$mysqli->set_charset("utf8");


$name = "Guilherme";
$s = microtime(true);
$stmt = $mysqli->prepare("insert into users(name) values(?)");
$stmt->bind_param("s",$name);
$mysqli->query("start transaction");
for($i =0;$i<10000;$i++){
  $stmt->execute();
}
$mysqli->commit();
$e = microtime(true);
echo ($e - $s) . PHP_EOL;

$mysqli->query("truncate users");
$mysqli->close();
