To improve Laravel app performance, use caching strategically, optimize database queries, reduce frontend payload, and offload heavy tasks with queues. First, implement Redis or Memcached for caching frequent data, route responses, and Blade templates while managing cache invalidation. Second, optimize queries by eager loading relationships, selecting only needed columns, indexing key fields, and using read replicas. Third, minimize frontend assets via minification, lazy loading, Laravel Vite, compression, and removing unused CSS. Fourth, dispatch long-running tasks like email sending or image processing to background queues using Redis or the database, with proper error handling and job batching.

Laravel is a powerful PHP framework, but as applications grow in complexity, performance can become an issue. Slow response times and high resource usage are common pain points for developers. The good news? There are several practical techniques you can apply to keep your Laravel app running smoothly without sacrificing maintainability.

Use Caching Strategically

Caching is one of the most effective ways to improve performance. Laravel provides multiple caching drivers like file, database, Redis, and Memcached. For most applications, using Redis or Memcached gives better performance than file-based caching because they’re faster and support more advanced features.

Here’s how to make caching work for you:

• Cache frequently accessed data (e.g., configuration values, heavy query results)
• Use route caching for APIs or static routes
• Blade templates can be cached too — Laravel does this by default
• Don’t forget about cache invalidation — stale data can cause bugs

For example, if you have a dashboard that shows aggregated user stats from multiple tables, consider caching the result for a few minutes instead of recalculating it on every request.

Optimize Database Queries

Slow queries are often the main bottleneck in Laravel apps. Even with clean code and solid architecture, inefficient database calls can drag performance down.

Here are some things you can do:

• Use dd() or Laravel Telescope to spot N 1 query issues
• Eager load relationships with with() instead of loading them inside loops
• Select only the columns you need (select(['id', 'name']))
• Index frequently searched columns in your database
• Consider using read replicas for heavy read operations

One common mistake is fetching all columns when only a few are needed. If you're displaying a list of users and only showing their names, there's no need to pull in their entire record.

Reduce Frontend Payload and Optimize Assets

Even if your backend is fast, bloated frontend assets can make your app feel slow. This includes large JavaScript files, unoptimized images, and excessive CSS.

To tackle this:

• Minify and combine JS/CSS using Laravel Mix
• Lazy-load images and non-critical scripts
• Use tools like Laravel Vite for faster builds
• Compress assets with Gzip or Brotli
• Remove unused CSS (PurgeCSS works well with Laravel)

If you're using a SPA with Vue or React, splitting your bundle into smaller chunks can significantly reduce initial load time.

Offload Heavy Tasks with Queues

Long-running tasks like sending emails, processing images, or generating reports should not block the main request thread. Laravel queues allow you to defer these tasks to background workers.

Tips for using queues effectively:

• Choose the right driver — Redis or database (Redis is faster)
• Handle failed jobs gracefully with retries and logging
• Use supervisors like Horizon or PM2 to monitor queue workers
• Batch jobs where possible to reduce overhead

For instance, if a user uploads a photo that needs resizing and watermarking, you can dispatch a job to handle it asynchronously so the user doesn't wait for the process to finish.

That’s basically it. These techniques aren’t magic, but applied together, they can significantly boost performance in Laravel apps. Some are easy wins, others require deeper setup — but all are worth considering depending on your project’s needs.
