When choosing a backend technology, performance is often the deciding factor. Developers frequently turn to benchmarks to compare options, and one question that pops up a lot is: how do Node.js and Go (Golang) stack up, especially in terms of concurrency? Both are popular choices for building scalable web applications, but their approaches to handling concurrent tasks differ significantly. This article dives into their performance differences, explores why Go often comes out ahead, and examines whether benchmark tests are truly fair. We’ll also look at real-world data from the TechEmpower Web Framework Benchmark and discuss how to optimize both technologies for maximum speed.
