Performance Symfony 1.4改进原则保存（）方法

我的数据库中有500个条目。在我的后台，我有行动。例如：

 public function executeMyAction(sfWebRequest $request) {

 // Get some data from table
 $templates = Doctrine_Core::getTable('SeoTemplates')->findOneByEntity('training');

//Get data from other table(500 items)
 $trainings = Doctrine::getTable('Training')->getTraining();

  // Make some operations with data
  foreach ($trainings as $training) {

       $training->setSomeValue1('some_data');
       $training->setSomeValue2('some_data');
       $training->setSomeValue2('some_data');

  }

// Problem part (try to save)
$trainings->save();
}

save（）执行了很长时间。如何解决这个问题？可能吗

在我的问题部分，我有所有已知的错误致命错误：在

保存每条记录而不是一个集合时，超过了30秒的最长执行时间

$templates = Doctrine_Core::getTable('SeoTemplates')->findOneByEntity('training');
$trainings = Doctrine::getTable('Training')->getTraining();
foreach ($trainings as $training) {
   $training->setSomeValue1('some_data');
   $training->setSomeValue2('some_data');
   $training->setSomeValue2('some_data');
   $training->save();
}

或者使用条令使用查询更新记录

$q = Doctrine_Query::create()
   ->update('TABLE')
   ->set($val1, '?', $val1)
   ->set($val2, '?', $val2)
   ->set($val3, '?', $val3)
   ->where('id = ?', $id)
   ->execute();

非常感谢。第二条路很快：-）
