As your application scales beyond millions of monthly requests, traditional synchronous request-response loops become the primary performance bottleneck.
Decoupling Workloads with Redis Pub/Sub
By delegating resource-intensive processes such as PDF generation, third-party webhook dispatch, and email notification pipelines to dedicated Laravel queue workers, API latency drops from seconds to under 40 milliseconds.
Database Connection Pooling
Ensure your MySQL or PostgreSQL connections are mediated by proxies like ProxySQL or PgBouncer to prevent connection exhaustion during high-concurrency traffic spikes.
