慢速法则查找

Question

我正在试图弄清楚为什么我的一个理论发现运行得如此慢。我真的不知道从哪里开始，所以请容忍我。

我做了一个非常基本的find来获取一个user对象。这个发现需要大约160毫秒。当我通过phpmyadmin运行查询时，它使用.7ms。

$this->em->find('Entities\User', $userId)

我已经尝试将skip-name-resolve添加到mysql的my.cnf中。用户表中的id字段被编入索引。我真的不知道还能尝试什么。如果我能提供更多的信息，请告诉我。

以下是实体文件：

namespace Entities;
use Doctrine\Common\Collections\ArrayCollection;
use Doctrine\ORM\EntityRepository;

/** @Entity(repositoryClass = "Entities\UserRepository")
  * @Table(name="user") 
  */
class User extends \Company_Resource_AbstractEntity
{
    /** @Id @Column(type="integer") @GeneratedValue */
    protected $id;
    /** @Column(type="string") */
    protected $name;
    /** @Column(type="string") */
    protected $password;
    /** @Column(type="string") */
    protected $email;
    /** @Column(type="string") */
    protected $first_name;
    /** @Column(type="string") */
    protected $last_name;
    /** @Column(type="integer") */
    protected $password_reset;
    /** @Column(type="string") */
    protected $salt;
    /** @Column(type="integer") */
    protected $active;
    /** @Column(type="string") */
    protected $cookie_hash;

    /**
    * @ManyToOne(targetEntity="Company" , inversedBy="user")
    */
    protected $company;

    /**
    * @ManyToOne(targetEntity="Privilege" , inversedBy="user")
    */
    protected $privilege;

    /**
    * @OneToMany(targetEntity="CompanySubscription" , mappedBy="user")
    */
    protected $subscription;

    /**
    * @OneToMany(targetEntity="EquipmentEvent" , mappedBy="check_in_user")
    */
    protected $check_in;

    /**
    * @OneToMany(targetEntity="EquipmentEvent" , mappedBy="check_out_user")
    */
    protected $check_out;

    /**
    * @OneToMany(targetEntity="GroupEvent" , mappedBy="check_in_user")
    */
    protected $check_in_group;

    /**
    * @OneToMany(targetEntity="GroupEvent" , mappedBy="check_out_user")
    */
    protected $check_out_group;

    /**
    * @OneToMany(targetEntity="Maintenance" , mappedBy="submit_user")
    */
    protected $maintenance_submit;

    /**
    * @OneToMany(targetEntity="Maintenance" , mappedBy="completed_user")
    */
    protected $maintenance_complete;

    /**
    * @OneToMany(targetEntity="UserLogin" , mappedBy="user")
    */
    protected $login;
}

抽象实体：

use \Doctrine\Common\Collections\ArrayCollection;

abstract class Company_Resource_AbstractEntity implements ArrayAccess
{
    public function offsetExists($offset)
    {
        return property_exists($this, $offset);
    }

    // The get/set functions should check to see if an appropriately named function exists before just returning the
    // property.  This way classes can control how data is returned from the object more completely.
    public function offsetGet($offset)
    {
        $property = new Zend_Filter_Word_UnderscoreToCamelCase();
        $method = 'get'. $property->filter($offset);
        return $this->{$method}();
    }

    public function offsetSet($offset, $value)
    {
        $property = new Zend_Filter_Word_UnderscoreToCamelCase();
        $method = 'set'. $property->filter($offset);
        return $this->{$method}($value);
    }

    public function offsetUnset($offset)
    {
        // can't do this
    }

    /*==-====-====-====-====-====-====-====-====-====-====-==*/

    /*
     * Provides magic method access for getFieldName() and setFieldName()
     * where field_name is a simple field and not a relation
     * A special getData implementation returns all of the current object vars
     */
    public function __call($method, $arguments)
    {
        preg_match('@^([a-z]+)(.*)@', $method, $matches);
        $action = $matches[1];
        $property = $matches[2];
        $underscore = new Zend_Filter_Word_CamelCaseToUnderscore();
        $offset = strtolower($underscore->filter($property));
        if ($action == 'get')
        {
            if ($property == 'Data')
                return get_object_vars($this);
            if ($this->offsetExists($offset))
                return $this->{$offset};
            else
                throw new Zend_Exception(sprintf("'%s' does not have property '%s'", get_class($this), $offset));
        }
        else if ($action == 'set')
        {
            if ($this->offsetExists($offset))
                return $this->{$offset} = $arguments[0];
            else
                throw new Zend_Exception(sprintf("'%s' does not have property '%s'", get_class($this), $offset));
        }
        else
            throw new Zend_Exception(sprintf("'%s' does not have method '%s'", get_class($this), $method));
    }
}

find生成的SQL：

SELECT t0.id AS id1, 
t0.name AS name2, 
t0.password AS password3, 
t0.email AS email4, 
t0.first_name AS first_name5, 
t0.last_name AS last_name6, 
t0.password_reset AS password_reset7, 
t0.salt AS salt8, 
t0.active AS active9, 
t0.cookie_hash AS cookie_hash10, 
t0.company_id AS company_id11, 
t0.privilege_id AS privilege_id12 
FROM user t0 WHERE t0.id = ?

有没有人看到什么不对劲的地方，或者知道该怎么做呢？

使用Doctrine 2.2.2。

我认为我的设置的问题在于文件中的实际行数。教义每次都会通读这些内容。我为元缓存启用了APC，在第一次加载后，加载时间大大减少。没有查询或结果缓存，查询实际上只需要大约6毫秒，这就是我一直以来的目标。真希望我能早点试一下。
