Slow Laravel applications lose users and revenue. This guide covers practical performance optimization techniques that work in production — from database queries to caching strategies to queue management.
I'm Riad Hasan , a full stack developer who has optimized Laravel applications handling millions of requests. Here are the techniques that actually make a difference.
The Performance Problem
