Some practical tips to improve Laravel 5 performance

Laravel is known for its elegance and simplicity, and there are many projects using the Laravel framework. However, its performance has always been a pain point that has been criticized. After all, performance has a very important impact on the project. This article will share with you some tips for Laravel 5 performance optimization.

1. Configuration cache information

Use the artisan command that comes with laravel to cache all configurations in the config into a file.

php artisan config:cache

All cache information will be stored in the bootstrap/cache/config.php file. You can also use the following command to delete the cache information:

php artisan config:clear

When the configuration information is modified, generally execute php artisan config:cache directly, because it will automatically execute php artisan config:clear first, Then execute php artisan config:cache.

2. Routing information caching

When there are more and more routes, especially in large projects, the effect of route caching is obvious.

php artisan route:cache

All routes will be cached in the bootstrap/cache/routes.php file. If you want to use route caching, then all routes cannot use closures. That is, in the form of an anonymous function. You can also use

php artisan route:clear

to clear the routing cache.

3. Class mapping loading optimization

optimize The command caches some commonly used classes into files to improve performance by reducing file loading. :

php artisan optimize --force

will generate two files bootstrap/cache/packages.php and bootstrap/cache/services.php.

In the production environment, the parameters --force do not need to be specified, the file will be automatically generated.

To clear class map loading optimization, run the following command:

php artisan clear-compiled

This command will delete the two files generated by optimize above.

Note: This command must be run after php artisan config:cache because the optimize command is based on configuration information (such as: config/ providers array of app.php file) to generate the file.

4. Use redis/memcached to store session session

Every laravel request will generate session session information. By default, the file storage method is used, which is stored in the storage/framework/sessions file. You can modify the storage method in config/session.php.

'driver' => 'redis',

5. Use a professional cache driver

"Cache" is one of the magic weapons to improve the running efficiency of applications. The default cache driver is file For file caching, it is recommended to switch to a professional caching system, such as Redis or Memcached. It is not recommended to use database caching.

You can modify the configuration file config/cache.php:

'default' => 'reids',
