How to Optimize Queue Performance in Laravel with Redis/Horizon?

Laravel has a well-structured queue system. It automates time-consuming tasks such as emails, billing and API calls. But as the app scales, using queues is not enough to handle high-traffic workloads. You need to optimize your queue performance with Laravel developer tools like Horizon and Redis. 

Why Use Redis and Horizon for Laravel Queues?

Redis + Horizon Advantages:

• Millisecond response times
• Real-time job monitoring
• Queue balancing and prioritization
• Dashboard with failed jobs & metrics
• Seamless scaling with supervisors

Step-by-Step: Optimizing Laravel Queues with Redis & Horizon

Step 1: Set Redis as Your Queue Driver

In your .env file, change the queue driver to Redis:

env:

QUEUE_CONNECTION=redis

Ensure Redis is installed and configured properly in config/database.php:

'redis' => [ 'client' => env('REDIS_CLIENT', 'phpredis'), // or 'predis' 'default' => [ 'host' => env('REDIS_HOST', '127.0.0.1'), 'password' => env('REDIS_PASSWORD', null), 'port' => env('REDIS_PORT', 6379), 'database' => 0, ],
],

Step 2: Install and Configure Laravel Horizon

Install Laravel Horizon:

Bash:

composer require laravel/horizon

Publish the configuration:

Bash:

php artisan horizon:install
php artisan vendor:publish --tag=horizon

Set up your Horizon configuration in config/horizon.php:

PHP:

'environments' => [ 'production' => [ 'supervisor-1' => [ 'connection' => 'redis', 'queue' => ['default', 'emails', 'notifications'], 'balance' => 'auto', 'processes' => 10, 'tries' => 3, ], ],
],

Run Horizon:

Bash:

php artisan horizon

Access Horizon Dashboard:

Step 3: Queue Job Optimization Tips

Use Specific Queues for Different Job Types

Tag jobs to specific queues to avoid bottlenecks:

PHP:

dispatch((new SendWelcomeEmail())->onQueue('emails'));
dispatch((new ProcessInvoice())->onQueue('invoices'));

Set up workers to prioritize queues:

Bash:

php artisan queue:work redis --queue=emails,invoices,default

Use chunk() for Large Datasets

Avoid dispatching 10,000 jobs at once. Use batching or chunking:

PHP:

User::chunk(100, function ($users) { foreach ($users as $user) { dispatch(new SendNewsletterEmail($user)); }
});

Set Job Timeout and Retry Limits

Avoid long-running or stuck jobs:

PHP:

class ProcessReportJob implements ShouldQueue
{ public $timeout = 60; // seconds public $tries = 3;
}

Use Laravel Batching for Grouped Jobs (Laravel 8+)

PHP:

Bus::batch([ new ExportUserData($user), new GeneratePDFReport($user),
])->dispatch();

Batching allows tracking status and results in groups — especially useful for dashboard tasks or exports.

Step 4: Advanced Horizon Performance Tips

Enable Auto-Balancing in Horizon

Horizon can automatically scale workers between queues:

'balance' => 'auto', // or 'simple', 'false'

Monitor Metrics in Real-Time

Horizon’s dashboard shows:

• Job throughputs
• Wait times
• Failed jobs
• Queue load

Use this data to adjust your worker count, retry strategies, or queue priorities.

Scale with Multiple Supervisors

In horizon.php, define multiple supervisors:

PHP:

'environments' => [ 'production' => [ 'emails-supervisor' => [ 'queue' => ['emails'], 'processes' => 5, ], 'payments-supervisor' => [ 'queue' => ['payments'], 'processes' => 10, ], ],
],

Run supervisors in the background using Supervisor (Linux service) or Forge.
