Laravel Performance Optimisation Flashcards
(25 cards)
What is performance optimization in Laravel?
Performance optimization in Laravel improves application speed and efficiency using caching, query optimization, and server tuning.
Like WordPress’s performance tuning (e.g., WP Rocket), Laravel optimization reduces load times for better user experience and SEO. Freelancers enhance client apps, while enterprise architects scale for high traffic, aligning with your WordPress and LAMP performance experience.
What is caching in Laravel?
Caching stores frequently accessed data to reduce processing, using drivers like file or redis.
Similar to WordPress transients, caching speeds up data retrieval. For example, Cache::put(‘key’, $data, 3600) stores data. Freelancers cache views, while enterprise architects use distributed caches, per your LAMP performance deck.
How do you cache data in Laravel?
Use Cache::put(), like Cache::put(‘users’, User::all(), now()->addMinutes(60)).
Stores data for 60 minutes, like WordPress’s set_transient(). Freelancers cache query results, while enterprise architects optimize cache duration, per your PHP database skills.
What is the Cache::remember() method?
Cache::remember() retrieves or generates cached data, like Cache::remember(‘users’, 3600, function() { return User::all(); }).
Reduces database calls, like WordPress’s caching plugins. Freelancers use it for APIs, while enterprise architects scale caching, per your API development deck.
How do you clear Laravel’s cache?
Run php artisan cache:clear to flush the cache.
Resets cached data, like WordPress’s delete_transient(). Freelancers clear caches during updates, while enterprise architects automate cache management, per your Laravel Fundamentals deck.
What is route caching in Laravel?
Route caching compiles routes for faster loading, using php artisan route:cache.
Improves routing performance, like WordPress’s permalink optimization. Freelancers cache routes in production, while enterprise architects ensure cache refreshes, per your Routing and Middleware deck.
How do you clear Laravel’s route cache?
Use php artisan route:clear.
Removes cached routes, like resetting WordPress permalinks. Freelancers clear during development, while enterprise architects manage cache lifecycles, per your performance focus.
What is view caching in Laravel?
View caching compiles Blade templates, using php artisan view:cache.
Speeds up rendering, like WordPress’s template caching. Freelancers cache views, while enterprise architects optimize template performance, per your Blade Templating deck.
How do you optimize Eloquent queries?
Use eager loading with with(), like User::with(‘posts’)->get().
Prevents N+1 query issues, like WordPress’s optimized WP_Query. Freelancers reduce queries, while enterprise architects scale data access, per your Eloquent ORM deck.
What is selective column retrieval in Eloquent?
Use select(), like User::select(‘id’, ‘name’)->get().
Reduces data load, like WordPress’s fields in WP_Query. Freelancers optimize queries, while enterprise architects minimize bandwidth, per your PHP database skills.
How do you paginate Eloquent results?
Use paginate(), like User::paginate(10);.
Limits results per page, like WordPress’s pagination. Freelancers paginate API responses, while enterprise architects optimize pagination, per your API development deck.
What is query caching in Laravel?
Query caching stores database results, like Cache::remember(‘posts’, 3600, function() { return Post::all(); }).
Like WordPress’s query caching, it reduces MySQL load. Freelancers cache queries, while enterprise architects use Redis, per your LAMP performance deck.
How do you optimize Laravel’s database connections?
Tune config/database.php, like setting connections.mysql.pooling = true.
Manages connections, like WordPress’s $wpdb optimization. Freelancers configure pooling, while enterprise architects scale connections, per your MySQL deck.
What is Laravel’s opcache for performance?
opcache caches compiled PHP bytecode, enabled in php.ini with opcache.enable=1.
Speeds up execution, like WordPress’s PHP caching. Freelancers enable opcache, while enterprise architects tune settings, per your PHP core concepts deck.
How do you optimize Blade templates?
Cache views with php artisan view:cache and minimize @php directives.
Reduces rendering time, like WordPress’s template optimization. Freelancers cache templates, while enterprise architects avoid inline logic, per your Blade Templating deck.
What is lazy loading in Laravel collections?
Lazy loading processes collections incrementally, like User::all()->lazy()->map(…).
Saves memory, unlike WordPress’s full post loading. Freelancers use lazy loading for large datasets, while enterprise architects optimize processing, per your Eloquent ORM deck.
How do you use Redis for caching in Laravel?
Configure config/cache.php with redis driver and use Cache::store(‘redis’)->put(…).
Like WordPress’s memcached, Redis boosts caching. Freelancers set up Redis, while enterprise architects scale distributed caches, per your LAMP performance deck.
What is Laravel Horizon for performance?
Horizon monitors and optimizes job queues, installed with composer require laravel/horizon.
Like WordPress’s cron jobs, it manages background tasks. Freelancers optimize queues, while enterprise architects scale job processing, per your deployment interests.
How do you optimize Laravel queues?
Use queue:work –tries=3, configure queue.php, and monitor with Horizon.
Ensures efficient task processing, like WordPress’s WP-Cron. Freelancers manage queues, while enterprise architects distribute workloads, per your LAMP deployment deck.
How do you optimize API responses in Laravel?
Use resources (UserResource), pagination, and caching (Cache::remember()).
Like WordPress’s REST API optimization, it reduces response size. Freelancers streamline APIs, while enterprise architects scale endpoints, per your API development deck.
What is HTTP caching in Laravel?
HTTP caching sets cache headers, like return response($data)->cacheFor(3600);.
Like WordPress’s mod_expires, it caches responses. Freelancers enable caching, while enterprise architects configure CDN integration, per your LAMP performance deck.
How do you profile Laravel performance?
Use Laravel Telescope or Debugbar, installed with composer require laravel/telescope.
Like WordPress’s Query Monitor, it analyzes queries and requests. Freelancers debug performance, while enterprise architects monitor metrics, per your debugging deck.
How do you optimize Laravel’s autoloader?
Run composer dump-autoload –optimize to generate an optimized autoloader.
Speeds up class loading, like WordPress’s plugin optimization. Freelancers run it during deployment, while enterprise architects automate it, per your PHP advanced techniques.
How do you scale Laravel for high traffic?
Use load balancers, queue workers, and database replication, configured in config/database.php.
Like WordPress’s multi-server setups, it handles traffic. Freelancers scale apps, while enterprise architects use cloud solutions, per your LAMP deployment deck.
