一，前言

装了，mysql proxy后感觉挺爽的，因为代码端就不要那边烦了。哈哈。但是实际运用时发现他慢啊，能明显感觉出来。郁闷

二，测试mysql proxy的效率情况

1），按常规方法，连接数据库

<?php
/*
* Created on 2009-12-8
*
* To change the template for this generated file go to
* Window - Preferences - phpeclipse - php - Code Templates
*/

$dsn = 'mysql:dbname=test;host=192.168.1.75;port=3306';
$user = 'root';
$password = '';

try {

$dbh = new PDO($dsn, $user, $password);

$sql = "SELECT id, name, sex ".
" FROM test ";

$sth = $dbh->prepare($sql);
$sth->execute();

$result = $sth->fetchAll(PDO::FETCH_ASSOC);
print_r($result);

} catch (PDOException $e) {
echo 'Connection failed: ' . $e->getMessage();
}

?>

测试结果：

mysql 正常连接

2），用mysql proxy，连接数据库

<?php
/*
* Created on 2009-12-8
*
* To change the template for this generated file go to
* Window - Preferences - phpeclipse - php - Code Templates
*/

$dsn = 'mysql:dbname=test;host=127.0.0.1;port=8888';
$user = 'root';
$password = '';

try {

$dbh = new PDO($dsn, $user, $password);

$sql = "SELECT id, name, sex ".
" FROM test ";

$sth = $dbh->prepare($sql);
$sth->execute();

$result = $sth->fetchAll(PDO::FETCH_ASSOC);
print_r($result);

} catch (PDOException $e) {
echo 'Connection failed: ' . $e->getMessage();
}

?>

测试结果：

mysql proxy 连接数据库

由上面二个测试结果，可以看出来，用了mysql proxy速度降了不是一点点，降了好几倍啊。我在网上找了一下，原因没有找到。汗。
