Why Database Connection Pool Size Tuning Still Matters in 2026

from Database Tech with Fexingo: SQL, NoSQL, and Data Storage Conversations · host Fexingo

In episode 42 of Database Tech with Fexingo, Lucas and Luna dive into the fine-tuning of database connection pool sizes, a topic that remains critical for performance in 2026. They explore the classic formula for pool sizing, explain why bigger pools don't always mean better performance, and walk through a real-world example: a Postgres application that saw a 40% latency reduction after cutting pool size from 100 to 25 connections. They also discuss how connection pool sizing interacts with connection latency spikes, read replicas, and retry strategies from prior episodes, and share practical heuristics for tuning. A must-listen for any engineer optimizing database performance. #DatabaseConnectionPool #ConnectionPoolSize #PostgresTuning #PerformanceOptimization #DatabaseLatency #TechPodcast #SQL #NoSQL #DataStorage #FexingoBusiness #BusinessPodcast #Technology #DatabaseScaling #DBTuning #Connections #BackendEngineering #DevOps #DatabaseArchitecture Keep every episode free: buymeacoffee.com/fexingo
