MongoDB VS Mysql 簡單測試.
廢話不多說.
MongoDB 使用 MongoDB Object Document Mapper測試.
Mysql 使用 Object Relational Mapper測試.
MongoDB部分:
config.php
register();
$classLoader = new ClassLoader('Doctrine\ODM\MongoDB', __DIR__ . '/../../lib');
$classLoader->register();
$classLoader = new ClassLoader('Doctrine\MongoDB', __DIR__ . '/../../lib/vendor/doctrine-mongodb/lib');
$classLoader->register();
$classLoader = new ClassLoader('Symfony', __DIR__ . '/../../lib/vendor');
$classLoader->register();
$classLoader = new ClassLoader('Documents', __DIR__);
$classLoader->register();
$config = new Configuration();
$config->setProxyDir(__DIR__ . '/Proxies');
$config->setProxyNamespace('Proxies');
$config->setHydratorDir(__DIR__ . '/Hydrators');
$config->setHydratorNamespace('Hydrators');
$config->setDefaultDB('doctrine_odm_sandbox');
//使用safe模式
$con = new Connection('localhost',array('safe'=>true, 'w' => 2,'wtimeoutMS' => 2000));
//使用一般模式
//$con = new Connection('localhost');
$reader = new AnnotationReader();
$reader->setDefaultAnnotationNamespace('Doctrine\ODM\MongoDB\Mapping\\');
$config->setMetadataDriverImpl(new AnnotationDriver($reader, __DIR__ . '/Documents'));
$dm = DocumentManager::create($con, $config);
測試新增用index.php
persist($Account);
$dm->flush();
}
$mtime = explode(' ', microtime());
$times=number_format(($mtime[1] + $mtime[0] - $starttime), 8);
echo "saft Inster time $times \n";
測試一般寫入1000筆:
$php index.php
Normal Inster time 14.19290113
測試saft寫入1000筆:
$ php index.php
saft Inster time 14.25004005
更新測試index.php:
更新七筆資料．
getRepository('Documents\Account')->find('4e382626e08239cbcf000027');
$Account_old->setName('Test Account'.rand(1,99999));
$dm->persist($Account_old);
$dm->flush();
$Account_old = $dm->getRepository('Documents\Account')->find('4e382626e08239cbcf000026');
$Account_old->setName('Test Account'.rand(1,99999));
$dm->persist($Account_old);
$dm->flush();
$Account_old = $dm->getRepository('Documents\Account')->find('4e382626e08239cbcf000025');
$Account_old->setName('Test Account'.rand(1,99999));
$dm->persist($Account_old);
$dm->flush();
$Account_old = $dm->getRepository('Documents\Account')->find('4e382626e08239cbcf000024');
$Account_old->setName('Test Account'.rand(1,99999));
$dm->persist($Account_old);
$dm->flush();
$Account_old = $dm->getRepository('Documents\Account')->find('4e382626e08239cbcf000023');
$Account_old->setName('Test Account'.rand(1,99999));
$dm->persist($Account_old);
$dm->flush();
$Account_old = $dm->getRepository('Documents\Account')->find('4e382626e08239cbcf000022');
$Account_old->setName('Test Account'.rand(1,99999));
$dm->persist($Account_old);
$dm->flush();
$Account_old = $dm->getRepository('Documents\Account')->find('4e382626e08239cbcf000021');
$Account_old->setName('Test Account'.rand(1,99999));
$dm->persist($Account_old);
$dm->flush();
$mtime = explode(' ', microtime());
$times=number_format(($mtime[1] + $mtime[0] - $starttime), 8);
echo "Update time $times \n";
使用apache ab做測試表示每個連線都對此7筆資料做更新.**

Mysql部分:
// Create EntityManager
$em = EntityManager::create($connectionOptions, $config);
## PUT YOUR TEST CODE BELOW
$mtime = explode(' ', microtime());
$starttime = $mtime[1] + $mtime[0];
for($i=1; $i<=10; $i++) {
$user = new User;
$user->setName('Test Account'.rand(1,99999));
$em->persist($user);
$em->flush();
}
$mtime = explode(' ', microtime());
$times=number_format(($mtime[1] + $mtime[0] - $starttime), 8);
echo "Inster time $times \n";

對不起我很懶… mysql新增部分就輸一倍了.
接下去就不測了．
結論:NoSQL粉快
看一下mongodb的log
Wed Aug 3 01:04:30 [conn12232] update doctrine_odm_sandbox.accounts query: { _id: ObjectId(‘4e382626e08239cbcf000022’) } byid 142ms
Wed Aug 3 01:04:27 [conn12035] update doctrine_odm_sandbox.accounts query: { _id: ObjectId(‘4e382626e08239cbcf000023’) } byid 629ms
這竟然是slow query!!!!!! WTF
