How Go Microservices Pay a Hidden Performance Tax—and How to Eliminate It

This article examines the often‑overlooked performance “tax” in Go microservices, detailing how misuse of goroutines, channels, interfaces, object allocation, and fan‑out patterns inflates CPU, memory, and tail‑latency costs, and provides concrete engineering strategies—such as request‑level concurrency limits, bulkheads, and efficient logging—to achieve production‑grade scalability.
