Answer 1

感谢@Zoran Stankovic 的想法，创建索引确实提高了速度，所以我不得不在模型中索引数据，参考creating-indexes

导入

use Illuminate\Support\Facades\Schema;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Database\Migrations\Migration;

我在模型上所做的代码示例

注册模式

public function regindex()
    {
        Schema::table('registrations', function (Blueprint $table) {
           $table->index('registration_id');
        });
    }

供客户回答

 public function customerindex()
    {
     Schema::table('customer_answers', function (Blueprint $table) {
      $table->index(['ssi_track_id','question_id']);
  });
 } 

对于 ssi_track 模型

public function ssiindex()
    {
      Schema::table('ssi_tracks', function (Blueprint $table) {
         $table->index(['ssi_track_id','registration_id']);
      });
    }
