Laravel low performance on json response - php

Question

In my Laravel application, the data are loaded via ajax for a data table. The performance is very bad. So I created a test script to measure the loading time.
public function index()
{
$mt1 = microtime(true);
$data = $this->repo->all();
$resource = ProjectResource::collection($data);
$response = response()->json($resource);
$mt2 = microtime(true);
dd($mt2 - $mt1);
}
There are 200 rows in the DB.
The model has 4 relations.
The script above takes> 6s to render the data.
If I uncomment the line $response = response()->json($resource);, the loading time is < 0.2s
What are the possibilities to speed up the render time for the JSON response?
The $data model:
Appends:
trait ProjectAttribute
{
public function getActionAttribute()
{
return $this->editButton().$this->deleteButton();
}
public function editButton()
{
if (Auth()->user()->can('update salesOrder')) {
return '<button data-toggle="tooltip" data-placement="top" title="'.__('buttons.general.crud.edit').'" class="btn btn-info btn-sm editProject mr-1" ><i class="fas fa-pen"></i></button>';
}
return "";
}
public function deleteButton()
{
if (Auth()->user()->can('delete salesOrder')) {
return '<button data-toggle="tooltip" data-placement="top" title="'.__('buttons.general.crud.delete').'" class="btn btn-danger btn-sm deleteProject" ><i class="fas fa-times"></i></button>';
}
return "";
}
public function getActiveLabelAttribute()
{
if ($this->active) {
return "<span class='badge badge-info'>Aktiv</span>";
}
return "<span class='badge badge-secondary'>Inaktiv</span>";
}
}
The model:
<?php
namespace App\Models\Project\Project;
use Altek\Accountant\Contracts\Recordable;
use Altek\Accountant\Recordable as RecordableTrait;
use App\Models\Traits\Uuid;
use Illuminate\Database\Eloquent\Model;
use Illuminate\Database\Eloquent\SoftDeletes;
class Project extends Model implements Recordable
{
use ProjectAttribute, ProjectMethod, ProjectRelationship, ProjectScope, Uuid, RecordableTrait, SoftDeletes;
protected $fillable = [
'name',
'description',
'sales_order_id',
'project_leader_id',
'project_type_id',
'project_status_id'
];
protected $appends = [
'action',
'activeLabel',
'salesOrderName',
'projectLeaderName',
'creatorName',
'statusName',
'statusLabel',
'typeLabel'
];
protected $with = ['projectLeader', 'salesOrder', 'projectType', 'projectStatus'];
}
The resource:
<?php
namespace App\Http\Resources;
use Illuminate\Http\Resources\Json\JsonResource;
class Project extends JsonResource
{
/**
* Transform the resource into an array.
*
* #param \Illuminate\Http\Request $request
* #return array
*/
public function toArray($request)
{
return [
'id' => $this->id,
'name' => $this->name,
'description' => $this->description,
'sales_order_name' => $this->salesOrder->name,
'sales_order' => $this->salesOrder,
'project_leader' => $this->projectLeader,
'project_leader_name'=> $this->projectLeader->full_name,
'creator' => $this->creator,
'creator_name' => $this->creator->full_name,
'type' => $this->projectType,
'type_name' => $this->projectType->name,
'type_label' => $this->projectType->typeLabel,
'status' => $this->projectStatus,
'status_name' => $this->projectStatus->name,
'status_label' => $this->projectStatus->statusLabel,
'created_at' => $this->created_at->format('Y-m-d'),
'action' => $this->action
];
}
}

Answer 1

There are several ways to profile a request to get some information as to what is taking the server so long to respond.
BlackFire - Which comes by default in Laravel Homestead in development or Laravel Forge for production
Laravel DebugBar - Can also be used in development (my personal favorite)
These will give you a lot more information regarding the parts of your code that may be taking time to complete and there are several more if you google around for Laravel or PHP profilers to find something that suits your needs.
