Case Study: Laravel Performance Optimization

Problem

A legacy Laravel API had p95 response times around 1200ms, with frequent slowdowns during peak traffic.

Technical audit

We identified N+1 query patterns, missing indexes, heavy serialization paths, and non-strategic cache usage.

Solution

We refactored query-heavy endpoints, tuned indexing, introduced targeted caching, and improved data-loading strategy.

Measured outcome

• p95 response time reduced from 1200ms to 220ms
• Peak-time error rate reduced by 41%
• Infrastructure cost reduced by 23% through lower database load
