Laravel Session Driver: File vs Memcached – Which One Is Better?

Sabuj Kundu 16th Jul 2025

Managing sessions efficiently is crucial for any Laravel application. While Laravel’s default file session driver works well out of the box, using memcached can offer better performance and scalability. In this post, let’s explore which one is right for you.

🔍 Quick Comparison

Criteria	File Driver	Memcached Driver
Performance	Disk-based I/O – slower	In-memory – extremely fast
Scalability	Not ideal for multi-server	Designed for distributed apps
Persistence	Persistent until cleanup	Volatile – lost on restart
Setup Complexity	Built-in, zero setup	Requires Memcached server + PHP extension
Concurrency	Locks can cause delays	No file locks, smooth handling
Garbage Collection	Laravel-managed	Memcached auto-evicts old data

✅ Choose File Driver When…

• You’re working in local development or staging.
• Your traffic is low to moderate and doesn’t require high throughput.
• You want simplicity—no extra setup, out-of-the-box working.

⚡ Choose Memcached Driver When…

• You’re running on multiple servers or a load-balanced environment.
• Your application handles high traffic—think large e-commerce or real-time features.
• You already use Memcached for Laravel caching or object caching.

🚀 How to Enable Memcached in Laravel

Interested in switching? Here’s a high-level overview:

1. Install and configure a Memcached server and php-memcached extension.
2. Update your .env file:
   SESSION_DRIVER=memcached
CACHE_DRIVER=memcached
3. Modify config/session.php to use the driver: 'driver' => env('SESSION_DRIVER', 'file').

That’s it—Laravel will now store sessions in-memory, giving you a noticeable boost in speed.

🧠 Beyond Memcached: Considering Redis?

If you’re aiming for data persistence and advanced features (like atomic operations or pub/sub), Redis can be an even better option. It brings durability, more capabilities, and works beautifully with Laravel.

📌 Final Takeaway

Use the default file driver for small or experimental projects. If you’re building something bigger—especially distributed, high-traffic, or performance-sensitive—go with memcached (or even Redis) for real benefits.
