緩慢教條尋找

Question

我想弄清楚爲什麼我的一個學說發現運行得如此緩慢。我不知道從哪裏開始，所以請耐心等待。

我做了一個非常基本的查找來獲取用戶對象。這個發現是~166毫秒。當我通過phpmyadmin運行查詢時，需要.7ms。

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

我已經嘗試添加skip-name-resolve到mysql的my.cnf。用戶表中的id字段被編入索引。我真的不知道還有什麼要嘗試。如果有更多我能提供的信息，請告訴我。

下面是實體文件：

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;

    protected $password_reset; 
    /** @Column(type="string") */ 
    protected $salt; 
    /** @Column(type="integer") */ 
    protected $active; 
    /** @Column(type="string") */ 
    protected $cookie_hash; 

    /**

    */ 
    protected $company; 

    /**

    */ 
    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; 
}

     } 
     else 
      throw new Zend_Exception(sprintf("'%s' does not have method '%s'", get_class($this), $method)); 
    } 
} 

的發現產生的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 = ? 

任何人看到任何錯誤或不知道去哪裏進一步與此？

我相信我的設置問題是文件中的行的實際數量：http://i.imgur.com/wWeGO.png

表架構。學說每次都在閱讀這些內容。我爲APC啓用了元高速緩存，加載時間在第一次加載後顯着下降。沒有查詢或結果緩存，該查詢實際上只需要大約6個MS，這正是我一直在追求的目標。希望我會盡早嘗試。
