Laravel, compared to PHP frameworks, is one of the leading ones. From launch in 2022, by Taylor Otwell only – it has been highly favored by each PHP developer for its elegant syntax, powerful features, and robust ecosystem.
Web development continues to evolve, and so do the demands placed on them. In 2023, Laravel Octane emerged as a transformative solution for scaling Laravel applications to meet the growing expectations of performance, concurrency, and responsiveness.
In this blog post, we’ll explore the boosters of Laravel Octane, the steps to use Laravel Octane to scale your application, and then the key benefits of using Octane in the Laravel application.
What is Laravel Octane?
Laravel Octane is a revolutionary package designed to add boosters to Laravel applications by incorporating the power of the Swoole extension for PHP. Initially introduced as an experimental feature in Laravel 8, Octane has matured into a stable and potent solution for building a high-performance web application.
Laravel Octane basically serves as a performance optimization tool that can significantly boost the speed and scalability of your Laravel web application.
By harnessing the fuel of the Swoole extension, Octane enables your Laravel application to operate as a long-lived, coroutine-based process. This means that multiple incoming requests can be handled concurrently, reducing latency and making your application more responsive.
Adopting Octane, you can achieve substantial performance improvements, reduced memory consumption, and the ability to effortlessly scale your web application to meet growing demands.
How Does Laravel Octane Work?
Laravel Octane works by optimizing the way a Laravel application handles incoming HTTP requests. It leverages the Swoole PHP extension, which provides a coroutine-based, event-driven architecture, allowing for greater efficiency and concurrent processing of requests.
Here’s a step-by-step explanation of how Laravel Octane works:
1. Swoole Extension
- Laravel Octane relies on the Swoole PHP extension. Due to this, you’ll need to first install the Swoole extension.
- You can do so, by running the following code snippet in the Composer:
composer require swoole/ide-helper
2. Application Initialization
- With Octane, Laravel initializes the web app only once.
- This means that the Laravel framework and application code are loaded once and cached for subsequent requests.
- Traditional PHP-FPM, on the other hand, initializes the framework for each request.
3. Asynchronous Execution
- Laravel Octane’s biggest advantage is its ability to handle multiple requests concurrently.
- While in a traditional Laravel application, you might process multiple requests sequentially.
- However, by using Swoole’s asynchronous capabilities, Octane can handle multiple requests concurrently.
// Traditional approach
$response1 = someTimeConsumingOperation();
$response2 = anotherTimeConsumingOperation();
// …
4. Stateful Workers
- Octane introduces stateful workers, which enable the maintenance of the application’s state across requests.
- This is particularly useful for a Laravel web app that requires shared in-memory data, such as WebSocket servers or long-polling real-time features.
// Octane example
$chatRoomState = [];
// State is maintained across requests
// Handle WebSocket connections and updates to $chatRoomState
5. Connection Management
- Octane application intelligently manages incoming connections and routes them to the appropriate worker processes.
- Each connection is served by the same worker throughout its lifespan, ensuring consistency and preventing data corruption.
6. Event Loop
- Open Swoole provides an event loop that allows non-blocking I/O operations.
- This is especially beneficial for tasks like handling asynchronous database queries, making external API calls, or serving WebSocket connections.
// Octane example
$response = await Http::get('https://example.com/api/data');
// Continue processing after the response is received
7. Request and Response Flow
- When handling concurrent requests in Octane, multiple requests can be processed at once.
- Middleware, route handling, and controller actions are executed concurrently, improving response times.
// Octane example
Route::get('/api/resource', function () {
// This code runs concurrently for multiple requests
});
8. Efficient Memory Management
- Octane optimizes memory usage by caching the Laravel app state.
- This reduces memory overhead and allows more memory to be available for handling concurrent requests.
9. WebSocket Support
- Octane provides built-in WebSocket support, allowing you to easily create real-time features.
- Here’s a simplified example of a WebSocket chat server:
// Octane WebSocket example
use Swoole\WebSocket\Server;
$server = new Server('0.0.0.0', 9501);
$server->on('message', function ($server, $frame) {
// Handle WebSocket messages here
});
$server->start();
10. Deployment
- Deploying Laravel Octane is straightforward. You can use Artisan commands to start and manage your Octane server.
- Here’s how you might start an Octane server:
php artisan octane:start

- This is typically done using Composer to require the Swoole package.
- You’ll need to ensure it’s properly configured for your server environment.
Step 3: Configure Octane
- Laravel Octane comes with its configuration file.
- This configuration file allows you to set options related to the number of workers, the application host, and other Swoole-specific settings.
- You can publish this configuration file and adjust settings to fit your application’s needs.
Step 4: Optimize Your Code
- Take advantage of Octane’s performance improvements by optimizing your Laravel codebase.
- Utilize caching, reduce database queries, and implement efficient algorithms.
- Consider using profiling tools like Laravel Telescope can help you identify bottlenecks and areas for improvement.
Step 5: Load Balancing
- To handle even more traffic, consider implementing load balancing with multiple Octane instances running on different servers.
- This Load Balancing will distribute incoming requests evenly and improve fault tolerance.
- Conducting this practice for your Laravel web app can help you ensure high availability, redundancy, and load distribution.
Step 6: Monitoring and Scaling
- Use monitoring tools like New Relic, Datadog, or other monitoring solutions to keep an eye on your application’s performance.
- When necessary, scale your infrastructure with horizontal scaling by adding more Octane instances or vertical scaling by upgrading server resources.
- Set up alerts for key metrics, and be prepared to scale your application horizontally/vertically as needed based on traffic patterns and resource utilization.
Thus, it’s crucial to continuously monitor, test, and optimize your application’s performance under Octane to ensure it meets your specific scaling requirements.
