🚀 REST vs gRPC Performance in Go: A Practical Benchmark-Driven Guide

When building high-performance microservices in Go, one question inevitably comes up: Should you use REST or gRPC? This isn’t just an architectural debate it directly impacts latency, throughput, infrastructure cost, and scalability . In this post, we’ll break down REST vs gRPC performance using real benchmarks, practical Go examples, and production insights. 🧠 Understanding the Core Difference Before diving into benchmarks, it’s important to understand why performance differs.
