Performance Optimization

Caching

Use Laravel's caching features to store frequently accessed data and reduce database load.

• Use drivers like Redis, Memcached, or file cache for different environments.
• Cache query results, configuration, and rendered views where appropriate.
• Use tags and expiration times to manage cache lifecycle.

Example:

// Store value in cache for 10 minutes
Cache::put('key', 'value', 10);
// Retrieve value from cache
$value = Cache::get('key');

• Use Cache::remember() to cache expensive queries automatically.

Database Optimization

Optimize database queries to improve performance and reduce resource usage.

• Use eager loading (with()) to avoid N+1 query problems.
• Select only required columns with select().
• Use indexes on frequently queried columns.
• Profile queries using Laravel Debugbar or Telescope.

Example:

// Eager load posts for users
$users = User::with('posts')->get();
// Select only name and email
$users = User::select('name', 'email')->get();

Queue Jobs

Use Laravel's queue system for long-running or resource-intensive tasks (e.g., sending emails, processing files).

• Use drivers like Redis, database, or SQS for queue management.
• Monitor and retry failed jobs using Laravel Horizon or built-in tools.

Example:

class SendEmailJob implements ShouldQueue {
    public function handle() {
        // send email
    }
}
// Dispatch a job
SendEmailJob::dispatch($user);

Best Practices

• Profile and benchmark application performance regularly.
• Use pagination for large datasets.
• Minimize use of synchronous/blocking operations.
• Optimize asset delivery (minify, compress, version static files).
• Monitor application performance in production and address bottlenecks.
