Symfony 4.4 getResult Hydrator 慢 - PHP 8.1

问题描述 投票：0回答：1

我将旧的 Symfony 4.3 应用程序更新为 4.4，并将该应用程序移至使用 PHP8.1 和 mySQL8 的新服务器上。在我使用 PHP7.4 的服务器之前。

我现在注意到我的应用程序在新设置上非常慢。 有些路线慢 1 秒，另一些则慢 4-5 秒。在旧系统上执行一个需要 7 分钟的非常大的命令，现在需要几个小时。

我的代码确实不完美，但这样的增加是不正常的。

例如，我发现了这个简单的数据库请求：

$queryBuilder = $this->em->createQueryBuilder()
        ->select("k")
        ->from(KVP::class, "k")
        ->andWhere("k.deleted = false")
        ->andWhere("(k.accept = 1 or k.deniedFrom is NOT NULL) and (k.done is NOT NULL or k.until is NULL)")
        ->addOrderBy('k.createdAt', 'DESC');
$queryBuilder->getQuery()->getResult();

当我将 getResult 更改为 getArrayResult 时，路线加载速度加快了 500 毫秒。在旧设置中，getResult 和 getArrayResult 之间的执行时间没有差异。

我需要对 PHP8 进行一些特定的配置还是需要更改代码？

以下是示例中 KVP 实体的摘录：

 namespace App\Entity\KVP;

     use App\Annotation\Acl;
     use App\Entity\Auth\User;
     use App\Entity\Employee\Department;
     use App\Traits\TableExtensionTrait;
     use Doctrine\ORM\Mapping as ORM;
     use Gedmo\Mapping\Annotation as Gedmo;
     use Symfony\Component\Validator\Constraints as Assert;

/**

 * @ORM\Entity(repositoryClass="App\Repository\KVP\KVPRepository")
 * @ORM\Table(name="t_kvp")
 *
 *

 */
class KVP
{
    // Includes create/update information
    use TableExtensionTrait;

    /**

     * @ORM\Column(type="integer")
     * @ORM\GeneratedValue(strategy="AUTO")
     * @var int
     */
    protected $id;

    /**
     * @ORM\OneToMany(targetEntity="App\Entity\ToDos\ToDos", mappedBy="kvp")
     */
    protected $todos;

    /**
     * @ORM\OneToMany(targetEntity="App\Entity\News\News", mappedBy="kvp")
     */
    protected $newsKVP;

    /**
     * @ORM\OneToOne(targetEntity="App\Entity\Chat\ChatGroup")
     */
    private $chatGroup;

    /**
     * @var User
     * @ORM\ManyToOne(targetEntity="App\Entity\Auth\User", inversedBy="kvp")
     * @ORM\JoinColumn(name="user_id", referencedColumnName="id", nullable=true)
     */
    private $user;

    /**
     * @var User
     * @ORM\ManyToOne(targetEntity="App\Entity\Auth\User", inversedBy="kvpResponsible")
     * @ORM\JoinColumn(name="userResponsible_id", referencedColumnName="id", nullable=true)
     */
    private $userResponsible;

    /**
     * @var Department
     * @ORM\ManyToOne(targetEntity="App\Entity\Employee\Department", inversedBy="kvpDepartment")
     * @ORM\JoinColumn(name="department_id", referencedColumnName="id", nullable=true)
     */
    private $department;

    /**
     * @var User
     * @ORM\ManyToOne(targetEntity="App\Entity\Auth\User", inversedBy="kvpAcceptedFrom")
     * @ORM\JoinColumn(name="acceptedFrom_id", referencedColumnName="id", nullable=true)
     */
    private $acceptedFrom;

    /**
     * @var User
     * @ORM\ManyToOne(targetEntity="App\Entity\Auth\User", inversedBy="kvpDeniedFrom")
     * @ORM\JoinColumn(name="deniedFrom_id", referencedColumnName="id", nullable=true)
     */
    private $deniedFrom;

    /**
     * @var string
     * @ORM\Column(name="title", type="text", nullable=true)
     * @Assert\NotBlank(message="field.not.blank")
     */
    private $title;

有人有同样的经历或知道我在这里缺少什么吗？

我想我可以将其范围缩小到水合学说。当我使用与其他实体有多个连接的实体创建 getResult 时，我遇到了性能问题。在旧设置/版本上 一切都好吗？

这是上面请求的 SQL：

SELECT t0_.id AS id_0, t0_.title AS title_1, t0_.problemState AS problemState_2, t0_.solution AS solution_3, t0_.accept AS accept_4, t0_.until AS until_5, t0_.inWork AS inWork_6, t0_.accepted AS accepted_7, t0_.comment AS comment_8, t0_.commentInWork AS commentInWork_9, t0_.deleted AS deleted_10, t0_.greenKvp AS greenKvp_11, t0_.done AS done_12, t0_.reminderSupervised AS reminderSupervised_13, t0_.lastReminderSupervised AS lastReminderSupervised_14, t0_.reminderAdmins AS reminderAdmins_15, t0_.lastReminderAdmins AS lastReminderAdmins_16, t0_.reminderSuperAdmins AS reminderSuperAdmins_17, t0_.lastReminderSuperAdmins AS lastReminderSuperAdmins_18, t0_.reminderOpen AS reminderOpen_19, t0_.lastReminderOpen AS lastReminderOpen_20, t0_.created_at AS created_at_21, t0_.updated_at AS updated_at_22, t0_.update_version AS update_version_23, t0_.chat_group_id AS chat_group_id_24, t0_.user_id AS user_id_25, t0_.userResponsible_id AS userResponsible_id_26, t0_.department_id AS department_id_27, t0_.acceptedFrom_id AS acceptedFrom_id_28, t0_.deniedFrom_id AS deniedFrom_id_29, t0_.created_by AS created_by_30, t0_.updated_by AS updated_by_31 
FROM t_kvp t0_ 
WHERE t0_.deleted = 0 
ORDER BY t0_.created_at DESC

当我仅选择几个与其他实体没有连接的字段时，服务器响应就很好。

这只是一个例子。问题在于我捕获与多个实体有连接的数据的每个地方。 （抱歉解释不好：））

我查看了两种设置上的 Symfony 性能结果，似乎问题不在于 Doctrine/Database。我毕竟是PHP，还是我对屏幕截图的解释错误？

Symfony 4.3 PHP 7.4 enter image description here

    ->andWhere("k.deleted = false")
    ->andWhere("(k.accept = 1 or k.deniedFrom is NOT NULL) and (k.done is NOT NULL or k.until is NULL)")

那个凌乱的

WHERE
闻起来就像是你在每个
SELECT
上添加的东西。 正确的？ 将其归结为一个标志，也许
is_valid
。 （如果需要，也保留详细信息。）我们无法优化这些东西。

向我们展示生成的 SQL 和 

SHOW CREATE TABLE
。 有了这些，我们可以帮助提高性能。
