Why Adding More Dubbo Connections Doesn’t Always Boost Throughput

This article examines Dubbo’s connection‑control feature, demonstrates how long‑living TCP connections are created, runs benchmark tests with one and two connections, discovers that varying IO thread counts skew results, and shows that increasing connections alone rarely improves throughput.
