How One Engineer Optimized an API with Connection Pooling

In this episode of The Software Engineering Podcast, hosts Lucas and Luna dive into a single, high-impact optimization: connection pooling. Lucas shares the story of an engineer at a mid-sized SaaS company who reduced API latency by 40 percent and cut database load by half just by tuning the connection pool settings. They break down what connection pooling is, the common misconfigurations that cause performance issues, how to monitor pool health, and how this specific engineer diagnosed the problem using latency percentiles and database query logs. The episode also covers the trade-offs between pool size, connection timeouts, and back-end resource limits, and provides actionable advice for listeners who want to audit their own connection pools. No fluff—just a concrete engineering win with numbers you can use. #ConnectionPooling #APIOptimization #DatabasePerformance #SoftwareEngineering #BackendEngineering #LatencyReduction #PostgreSQL #MySQL #NodeJS #Python #Java #PerformanceTuning #DatabaseConnection #TechPodcast #EngineeringPodcast #FexingoBusiness #BusinessPodcast #CodeOptimization Keep every episode free: buymeacoffee.com/fexingo
