当数据超过10k时，Laravel数据加载缓慢

Question

加载超过10k记录时性能缓慢

页面加载:8.00秒

问题:当数据超过10k时，是否会遇到类似的问题，返回数据的速度会变慢？有优化你的主意吗？当用户访问页面时，即使我已经在表中索引，加载所有数据也需要将近8秒的时间。

Answer 1

将代码更改为：

$player = Player::where('parent_id', Auth::user()->id)
      ->with(['getGames' => function ($q){
          $q->select('id', 'title', 'display_name');
  }])
  ->orderBy('created_at', 'desc');

  return Datatables::eloquent($player)
  //....

Answer 2

取消注释serverSide:真正的和

移除这个

->get()->toArray();

并将其替换为：

->latest();
