Learn how to construct a low‑latency, scalable WebSocket server in Go using fasthttp, custom read/write pumps, priority message queues, a worker‑pool, and Prometheus metrics, with full source code, detailed module explanations, and deployment instructions for real‑time high‑concurrency applications.
This article examines why Go’s fasthttp library can outperform the standard net/http package by up to tenfold, covering memory allocation strategies, zero‑copy techniques, connection pooling, and additional optimizations, and offers guidance on when to choose each library for high‑performance backend services.
This article compares Go’s standard net/http library with the high‑performance fasthttp server, detailing their request‑handling workflows, explaining fasthttp’s optimizations such as connection reuse, sync.Pool and unsafe.Pointer conversions, and walking through core code structures like workerPool, workerChan, and the Serve routine.
This article compares the performance of three HTTP server implementations—Java FunTester, Go's net/http, and the fasthttp library—by measuring QPS, CPU usage, and memory consumption across 1, 5, and 10 concurrent threads, and concludes that fasthttp consistently outperforms the others.
The article presents a detailed performance comparison of three HTTP client implementations—Java FunTester, Go's net/http, and the high‑performance fasthttp library—across multiple thread counts and artificial latency settings, reporting CPU usage, memory consumption, and QPS to determine the most efficient choice.
After mastering Go's net/http and fasthttp client libraries, this article presents six distinct server‑side implementations—ranging from basic net/http handlers to Echo, Gin, and fasthttprouter—highlighting their syntax, readability, and configuration differences for rapid backend development.
This article explores the fasthttp library as a high‑performance alternative to Go's net/http client, demonstrates basic and advanced API usage with object pools, shows how to set up a mock test server, and provides complete Go unit‑test examples with output verification.
