How We Reduced Webhook Delivery Latency by 40%
In Q3 2024, our monitoring showed a 120ms spike in median delivery times across our EU-West endpoint. Pieter van Dijk, lead backend engineer, led a deep-dive into our queue architecture. The culprit: synchronous TLS handshakes on cold-started containers. By implementing connection pooling with keep-alive strategies and pre-warming our Strapi and Shopify relay nodes, we brought P95 latency down from 340ms to 187ms. Read the full post-mortem and the open-source connection pool config we published to GitHub.
