Speed Up Laravel on Top of Swoole

Speed Up Laravel on Top of Swoole image

Swoole is a production-grade async programming framework for PHP. It is a PHP extension written in pure C language, which enables PHP developers to write high-performance, scalable, concurrent TCP, UDP, Unix socket, HTTP, WebSocket services in PHP without too much knowledge of the non-blocking I/O programming and low-level Linux kernel. You can think of Swoole as something like NodeJS but for PHP, with higher performance.

Why run Laravel on Swoole?

The image below illustrates the lifecycle in PHP. As you can see, when you run php script every time, PHP needs to initialize modules and launch Zend Engine for your running environment. And your PHP script needs to be compiled to OpCodes for Zend Engine’s execution.

However, this lifecycle needs to go over and over again in each request. Because the environment created for a single request will be immediately destroyed after the request process is done.

In other words, in traditional PHP lifecycle, it wastes a bunch of time building and destroying resources for your script execution. And imagine in frameworks like Laravel, how many files does it need to load for one request? There’s a lot of I/O consumption for loading files as well.

So what if we have a built-in server on top of Swoole, and all the scripts can be kept in memory after the first load? This is why we try to run Laravel on Swoole. Swoole can be a powerful performance booster and Laravel provides the elegant structure and code usages. That’s a perfect combination!

Installation

Here are the main features of swooletw/laravel-swoole:

  • Run Laravel/Lumen application on top of Swoole.
  • Outstanding performance boosting up to 30x.
  • Sandbox mode to isolate app container.
  • Support running WebSocket server in Laravel.
  • Support Socket.io protocol.
  • Support Swoole table for cross-process data sharing.

Require this package with Composer:

$ composer require swooletw/laravel-swoole

This package relies on Swoole extension. Make sure you’ve installed Swoole before you use this package. Using this command to install it quickly:

pecl install swoole

After installing the extension, you will need to edit php.ini and add an extension=swoole.so line before you use it.

php -i | grep php.ini # check the php.ini file location
sudo echo "extension=swoole.so" >> php.ini # add the extension=swoole.so to the end of php.ini
php -m | grep swoole # check if the swoole extension has been enabled

Visit the official website for more information.

Notice: Swoole currently only supports Linux and OSX. Windows servers are not able to use Swoole yet.

Then, add the service provider:

If you are using Laravel, add the service provider to the provider’s array in config/app.php:

[
'providers' => [
SwooleTW\Http\LaravelServiceProvider::class,
],
]

If you are using Lumen, append the following code to bootstrap/app.php:

$app->register(SwooleTW\Http\LumenServiceProvider::class);

It supports package auto discovery. If you’re running Laravel 5.5, you can skip this step.

Up and Running

Now, you can run the following command to start Swoole HTTP server.

$ php artisan swoole:http start

Then you can see the following message:

Starting swoole http server...
Swoole http server started: <http://127.0.0.1:1215>

Now you can access your Laravel application on http://127.0.0.1:1215.
