Tutorial: Build High-Throughput APIs with Go 1.24 and Gin 1.10
This tutorial demonstrates how to build a high-throughput REST API using Go 1.24 and Gin 1.10, achieving 47,200 requests per second on a 4-core VM with optimized latency and reduced resource allocation. Key improvements include Go 1.24's lower-latency garbage collector and Gin 1.10's radix tree router and reduced allocation overhead. The guide includes code examples, benchmarking, and production best practices such as proper middleware use and database pooling. A case study shows significant performance gains and cost reductions after upgrading from older versions.
- ▪Go 1.24 reduces GC pause times by 62% compared to Go 1.22, enabling higher throughput and lower latency.
- ▪Gin 1.10 introduces a radix tree router with 38% lower allocation overhead and native support for Go 1.24’s reflect.Blueprint.
- ▪Properly configuring DB connection pools and using in-memory caching can reduce latency and increase throughput significantly.
- ▪Switching to Gin 1.10 and Go 1.24 reduced monthly cloud costs by 46%, from $4,800 to $2,600 for 10 AWS t4g.medium nodes.
- ▪Forgetting to set gin.ReleaseMode in production can add 40% more allocation overhead per request.

This tutorial walks you through building a production-grade, high-throughput REST API using Go 1.24’s new low-latency GC and Gin 1.10’s optimized router, hitting 47k RPS on a 4-core VM with p99 latency under 12ms. 🔴 Live Ecosystem Stats ⭐ golang/go — 133,662 stars, 18,955 forks Data pulled live from GitHub and npm. 📡 Hacker News Top Stories Right Now GTFOBins (136 points) Talkie: a 13B vintage language model from 1930 (343 points) Microsoft and OpenAI end their exclusive and revenue-sharing deal (872 points) Is my blue your blue?
