Laravel queued jobs processed immediately even with a delay

I'm currently developing my personal application that is about private servers (for example, Minecraft servers) and since querying the server takes some time, I decided to implement queued jobs. However, they are not working properly, and they run immediately when called even though they are delayed, causing a massive latency in a page request.

Here's my HomeController's index() which calls the job to update every server with a 30 seconds delay:

public function index()
{
    $servers = Server::all();

    foreach($servers as $server)
    {
        // Job Dispatch
        $job = (new UpdateServer($server->id))->delay(30);
        $this->dispatch($job);
    }
    return view('serverlist.index', compact('servers'));
}

The job class that updates the servers is the following:

class UpdateServer extends Job implements SelfHandling, ShouldQueue
{
    use InteractsWithQueue, SerializesModels;
    protected $id;

    public function __construct($id)
    {
        $this->id = $id;
    }

    public function handle(){
        $server = Server::findOrFail($this->id);

        // Preparing the packet
        $test = new RAGBuffer();
        $test->addChar('255');
        $test->addChar('1');
        $test->addShort(1 | 8);

        // Finding the server
        $serverGame = new RAGServer($server->server_ip);

        // Get server information
        $status = $serverGame->sendPacket($test);

        $server->onlinePlayers = $status->getOnline();
        $server->peakPlayers = $status->getPeak();
        $server->maxPlayers = $status->getMax();

        if (!$server->save()) {
            // Error occurred
        }
    }
}

Whenever the HomeController's index() is run, there's a massive delay in the page request. I followed the tutorial at Laravel's Official Webpage, and I tried to find answers, but I didn't find anything.

So, what am I doing wrong? Why isn't the job getting delayed 30 seconds and then doing this in background in my server?

Also: The handle() is doing what it is supposed to. It queries the server, sends packets, and updates my database with the correct information.

Solution

You have to set up the queue driver you want to use in your project's root dir's .env file.

By default, the queue driver is sync which does exactly what you are describing, executing queues immediately.

You can choose of some different queue drivers, such as beanstalked or redis (which would be my choice). There's an excellent freebie on laracasts.com about setting up a beanstalked queue.

To view all available queue driver options in Laravel, have a look here.

Here's a .env example

APP_ENV=local
APP_DEBUG=true
APP_KEY=SomeRandomString

DB_HOST=localhost
DB_DATABASE=homestead
DB_USERNAME=homestead
DB_PASSWORD=secret

CACHE_DRIVER=file
SESSION_DRIVER=file
QUEUE_DRIVER=sync      // <-- Put the desired driver here

MAIL_DRIVER=smtp
MAIL_HOST=mailtrap.io
MAIL_PORT=2525
MAIL_USERNAME=null
MAIL_PASSWORD=null
MAIL_ENCRYPTION=null
